	matrix() could have been called with the same variable for two
		iterators (4 not ok/30 skip, but segfaults on exit)
	T: move failing tests to will_fail.t;

after 0.8:
	Hi-resolution plotting works if one has Term::Gnuplot v. 0.4,
		one needs to call link_gnuplot() before doing this;
	foncpari.pl now suggests the code for a missing interface (in simplest
	interfaces for most functions added (except buch*, string and addhelp);
	indirect variables (like PARIvar('x')) can be indexed like $x->[2];
	T: Interactive plotting test added (ignored if no Term::Gnuplot);
	Bug in libPARI/plotport.c corrected;
	Minor changes to chap3_to_pod;
after 0.91:
	Chip recognition code from PARI2.0alpha0 added;
	Builds on Solaris, gives illegal instruction trap in t/Testout.t:32;
after 0.92:
	Fix the failure on Solaris via aliasing shifts() to pari_shifts()
	(was dynalinking with libnls instead).
after 0.93:
	Updated for newer Term::Gnuplot.

after 0.94:
	Updated for v 2.0.11-beta of PARI.
	One needs to manually copy paricfg.h from pari distribution
		to libPARI directory.
	Processor recognition is on level of 2.0.5-alpha.
	sparcs on linux/nextstep not supported.
	hppa cannot build dynamically, use machine=port instead in
		Makefile.PL line.
after 0.95_00:
	Approximately half of subtests are passed now (229 skip, 337 fail
		out of 782).
	Some more patches to PARI are required (in ./patches).
	Still needs to be built as a subdirectory of the root of PARI tree.
after 0.95_01:
	Tests and paricfg.h are autocopied (but paricfg.h should be
	created first by toplevel configure script!).
	Skip compatibility tests.
	Circa 80% of non-skipped tests is OK (110 fail, 764 skipped
		out of 1381).
	Look for PARI build directory nearby.
	Autogenerate libPARI.pod.
after 0.95_02:
	Tag :prec=digits allowed.
	Overloaded << and >> (in Perl, not XS).
	Hex and octal conversion on _hex_cvt.
	Untested overloaded constants, on :int, :float, :hex import tags.
	Output of doubles explained.
	Flexible interface implemented (with runtime-parsing of
		signature, will not work if sizeof's char*, GEN, long 
		are different.)
		85% pass (366 skipped, 146 fail out of 1381).
			(nfields: some actually-wrong answers?)
after 0.95_03:
	Prototype for flexible-interface functions was wrong.
	Only type()/sumalt()/prodinf()/plot*() are special-cased in
		tests now (in addition to what was in 1.39).
	Better massage of matrix output, use RE to process pari output.
	undef allowed as a value of an optional argument.
	Minor massage of codes to move 'l' and 'v' forward.
	setseriesprecision() implemented.
	sv2pari() was not calling mg_get().

All tests successful, 1 test skipped, plus 156 subtests skipped.
Files=17,  Tests=1393, 204 secs ( 0.00 cusr  0.00 csys =  0.00 cpu)
		       ^^^ with debugging enabled

after 2.0011_01:
	Build which needed a translation to level0.s, kernel1.s was busted.
	Perl 5.005_52 had conflicting `warner'.
	Perl 5.005_52 has different order of hashes => needed to explicitly
		order the variables in Testout.pm.
	Perl 5.005_52: Autoloading got in the way of FETCHSIZE (implemented)
	:int, :float and :hex import tags tested and fixed.

All tests successful, 1 test skipped, plus 156 subtests skipped.
Files=15,  Tests=1377, 121 wallclock secs ( 0.00 cusr +  0.00 csys =  0.00 CPU)

after 2.001102:
        Patching was still busted.
	Use the copy of tar.gz in the current directory if present.

after 2.001103:
        Tests now run with the plotting enabled too.

All tests successful.
Files=15,  Tests=1378, 108 secs (86.46 cusr  3.82 csys = 90.28 cpu)

	new patch for PARI 2.0.12.
	Allow a LF before comma for my_print* tests.
	Special-case version 2.0.13 too (prefer alpha over betas).
	First step to allow dynalinking set_output_file().
	Change interfaces 83 and 84: they are void now.
	During test environment variable MP_NOGNUPLOT may be set to
	not load Term::Gnuplot.
	The hack to fake GEN-as-an-array-reference was creating a
	cyclic reference loop ==> memory leak.
	machine=port target was trying to compile none/level0.s.
	Special-case version 2.0.14 too (prefer alpha over betas).
	machine=port target was trying to compile src//level0.c.
	New patch for issqrt() - was wrong signature.
	Correct backwacking of \s \d.
	Default to `port' for unknow architectures.
	perl -MMath::Pari=:int -e 'for ($i = 1; $i < 10; $i++) {print "$i\n"}'
	     not fixed yet.  (Sometimes segfaults, prints floating points.)
		 (Solution: Make Perl use mymalloc, or upgrade to
		  5.00557 - maybe 5.00505 will also contain the fix.)
	New patch for signatures.
	Die on a wrong import tag, add link_gnuplot() to :graphic.
	Support DV and DI argument declarations, and new code 28 for vector().
	Fix handlers for codes 45 and 49.
	Now keep log of codes as supported by Math::Pari, as
	 implemented by PARI, and have a tool to check this (see libPARI/).
	Make test script creation skip backups and other junk.
	Update assembler-handling logic to 2.0.15-pre level,
	streamline logic a little bit.
	Tested with 2.0.14 and 2.0.15-pre+patches.
	On Linux RedHat 6.0: err was masked by some other dynamic library.
	Make plotting tests work again even without Term::Gnuplot.
	On Linux RedHat 6.0: one subtest of all.t (ellinit) fails, same with
	pure PARI.
	Add autopatches for 2.0.15 (it looks to stay).
	Link with Term::Gnuplot was using a wrong version of link_gnuplot().
	Better reports if run with redirections.
	Updated for 2.0.16.

	Change references to PARI types to t_FOO style.
	Assignment to elements of arrays implemented (probably wasteful).
		   (Can more tests be unskipped?).

	Update for new 'E' key of the interface string.
	Do not consider CVS as a test.

	Support overloaded binary constants, as in 0b1101.
	Support overloaded bitwise operations | & ^ ~ .

	->import() could only be called once due to caching of
	@EXPORT_OK by Exporter.  Thanks to
	thumper@bsi.menlo-park.ca.us for detecting the reason.

	hex() can return a float in newer perls, so overloaded hex
	constants would not work.  Thanks to
	thumper@bsi.menlo-park.ca.us for detecting the reason.

	Exporting the same symbol several times (e.g., to different
	packages) gave spurious warnings.

	Problems to fix yet: ++ floatifies; pari2iv() has a
	32-bit upper bound on 64-bit perls; problems with refcounting
	of array elements and Mod().

	Some declarations needed to be changed for multi-threading compile.

	ploth test was failing, since fake_sizes() was removing a Perl
	array, thus the arithmetic was propagating to double, =>
	problems when PARI sees arguments of a wrong type.
	gphelp updated.
	Remove patches to older version of PARI.
	Fix floatification in $a++ (but the choice of conversion to
	float/int may still be wrong in some cases).

	PARI version would not be calculated correct if Math::Pari is
	in a subdirectory of PARI directory.
	libPARI/gphelp was time-compared with one of PARI, but the
	latter one is autogenerated, thus has a random date.
	int() overloaded if possible.
	Conversion of large PARI's integers to Perl types would not
	croak, but will do as good as it can (should be as in perlnumber.pod).

	On solaris we were aborting if could not find SUNWspro - whose
	libraries we do not use any more!
	Overloading operator for int() had wrong number of parameters;
	In 5.7.1 I needed to change shift to CORE::shift in test_eng/Testout.t.
	New module Math::PariInit.
	New function setprimelimit().

	Math::PariInit would not set $initmem.
	allocatemem() implemented.

	Overloaded << and >> were using Perl's 2 instead of PARI's 2.
	(Need to be rewritten anyway! - but need to add a flag "Behave
	as if module large power of 2" to PARI's shift() first.)
	allocatemem() would not compile on 5.005.

	gcc build on sparc was busted.
	build on 5.00404 was busted.
	Copy pre-cooked Win32's paricfg.h without Configure'ing GP/PARI.
	Make README, INSTALL a little bit more clear.

	Was looking for Win32 paricfg.h at a wrong (obsolete) location.
	Globbing on Win32 misses gp/gp.c.  Put a workaround.

	Movement of PARI headers (in 2.001804) broke the compile on
	some misconfigured systems, which include
	/usr/include/sys/dl.h, which declares ladd.  Protect by
	temporary redefining ladd (we do not use it from Pari.xs).

	Use extraction of the version suggested by Karim Belabas.

	zcat replaced by gzip -dc, since zcat may not be able to
	handle gz.

	Generate libPARI/paricfg.h ourselves (t/elliptic.t:41 fails
	  unless we unconditionally define NOEXP2).
	Minor updates to INSTALL, change PARI to GP/PARI in messages
	  of Makefile.PL too.
	Wrap the code to get assembler version in alarm().
	More verbose message on reverting to 'port'.

	Improve README and INSTALL.
	Include <time.h> if USE_TIMES (advised by Bernhard Graf <fisch@augensalat.de>).
	Allow more precision loss in ellinit() - the current precision
	is unportable.
	[An attempt to loosen precision requirements break linear.t in
	unrelated places???  See test_eng/Testout.pm.]

	When generating paricfg.h, scan headers for getrusage, ulong,
	  CLK_TCK and ladd (the latter not used yet).
	Do not define ladd, just undef it after PARI headers are included.
	paricfg.h was rebuild too aggressively...
	Exclude gp/gp_init.c from inclusing into libPARI$(LIB_EXT).

	Significant update to documentation in Pari.pm.
	Tone down the warning on error of the pipe from cpp.
	New functions:   lg($x) lgef($x) longword($x, $n) type_name($x)
	t_STR is converted to a string without enclosing "".

	Patch for broken 2.1.2 (gccism).
	Was trying to compile kerneltest.c.
	lgefint($x) added.

	Allow trailing K, M, G in :stack=, :primes= directives of PariInit.pm.
	Recognize that GP/PARI may be in a directory named 'pari' (CVS).

	Would compile whatnow.o.  On the architectures with barely
	working dynalinking (cygwin only?) leads to unresolved symbols.
	Document the possible -fPIC limitation.

	On OS/2 DLOPEN was not supported well enough.
	More verbose messages about generation of paricfg.h.
	Support type 'M' of arguments (only numberic arguments, though).

	Better support of GNU as.
	New Makefile.PL options PARIDIR=directory
	Treat underscores in assembler files better.
	Recode brutcopy in terms of gcopy_av (not exported?).
	In 2.2.* branch: plotting and objet:22 tests segfault...
	Create XS functions good for left-right shift (buggy in 2.2.2?).

	Support quick <<, >> with newer PARI (2.2.*).
	Some tests still segfault with newer PARI...

	Set AMSINLINE if needed.
	Put obsolete files and utils in a subdirectory.

	Move a lot of code of Makefile.PL to Math::PariBuild.pm.
	(But DEFINE= processing still extremely messy.)
	New option force_download to Makefile.PL.
	PARIDIR= and MACHINE= were not removed from @ARGV.
	Sanity check: correspondence between numeric and string interfaces.
	Define GCC_INLINE if the compiler is gcc.
	New target `build_tests' for make.

	Misprint in PariBuild.pm fixed (thanks to John Borwick).

	Remove .pod on `make clean'.
	Do part of `perl -V' from Makefile.PL.
	Support 64-bit longsize.
	Fix for broken gcc 2.95 with -ffast-math.
	gpui() (for **) was called with wrong signature...
	0b1011 etc now should work
	$obj->can($meth_name) method implemented (AUTOLOAD-aware).
	Better 'skipped' messages
	Less tests skipped
	  (in graph: plot() - can't redirect output?!)
	  (in objets: error test?!)
	  (in program: f(x)=, print of a matrix, input(), break(),install())
	Support the current implementation of 'M' code.
	[Support for '&' code is still very hard to use - see test engine.]
	Do not define UNIX and USE_TIMES on Win32 (d_times *is* defined?!)
	Support M$ VC and Borland archive-creation switches and VC's
	  object-file destination switch.
	Use documented forcecopy instead of undocumented gcopy_av() [should
	  fix problems with destruction of Mod() too - but slower...].
	Whitespace edits in Perl code.
	Inheriting from Math::Pari lead to recursion in sv2pari().
	  [???  Similar change done to findVariable - not tested]
	Disable assembler on Win32 if not cc == gcc (won't understand GNU
	  assembler anyway).

	Special-case -o for object files for Borland too.
	Inline none/int.h for 2.2.5 or newer too.
	Define SHELL_Q (needed for 2.2.5).
	Adjust svputs to "const" for 2.2.5 or newer.
	Adjust _gtodouble() for 2.2.5 or newer.
	New way of generation of mp.c for 2.2.5 or newer.
	Backslashes in PARIDIR argument could confuse the test engine.
	Support of code 'M' (for mneumonics) was not complete.
	M$ VC can't handle files with .s extension, rename to kernel1.c if needed.
	Enable back default x86 build with Win32 compilers.

	Remove dead code for gcopy_av().
	[Confirmed that it builds on Win32 with M$ VC and mingw for both
	  'none' and 'ix86'.  (One needs to manually edit t/*.t.)  All the
	  hard investigative work was done by Bob "Sisyphus".  Thank him!]
	directory-with-\-support in test engine was flacky.
	CPPMINUS was not used.  Change CPP's %Config from cppstdin to cpp.
	Support for '&' is not very optimized, but works; just omit '&'.

	Cursory support for LIBPARI="-L/lib -lpari"
		spoofed version;
		no graphing functions present;
		bad free() at t/Pari.t line 265
			(calling installed Perl function from PARI)
		no PARI tests to convert;
		no POD to create;
		no check for ep codes;
		no patching the source;
	   [All but the first 3 of the problems can be avoided if one
	    lets Makefile.PL download and patch PARI, then builds the library
	    using the downloaded+patched version.]
	 Possible problems:
		different sizeof(long);
		non-compatible threading model;
		-lpari build with different non-compatible compiler;
	Cosmetic changes to TestOut.
	Allow running tests from a different directory (non-Unix filespec?).
	Somehow the patches to 2.1.4 were not applied.  Apply them to 2.1.5 too.
	May download via LWP (thanks to Slaven Rezic).

	Autogenerate valence tables func_codes.h by code_C_translator()
  perl -I utils -MMath::PariBuild -wle "print code_C_translator">func_codes.h
		and use	them from Pari.xs instead of EpVALENCE(ep)
		[which is now used to distinguish user functions only].
			[Workaround for bug in C_constant...  XXXX]
	-DLONG_IS_64BITS is detected in Math::PariBuild and put in paricfg.h.
	Rename t/Pari.t to t/00_Pari.t
	XS((*subaddr)) moved out of function ('dllexport' attribute on cygwin
		is not compatible with static).
	Always define DL_DFLT_NAME as NULL.
	Remove GCC_INLINE if perl is build with -g (needed with 2.1.5 too).
	Misprint in wrongT() [unused function].
	Do not use -O1 for assembler on alpha (not supported any more).
	Document the licence terms.
	Make C code C++-compatible: rename new.
	Do not use undecleared killblock0().
	Support error messages of the form (calling PARI('O(det2($mat))')):
PARI:   ***   obsolete function: O(det2($mat))
	Try to retry with Passive FTP if the default fails (untested).
	Update the list of files to append to libPARI/mp.c up to 2.2.7.
	Compensate to missing bruteall().	XXXX
	Compensate for new "gettime;" idiom in the tests.
	Need to add this on OS/2:
os2$(OBJ_EXT): $(PARI_DIR)/src/systems/os2/os2.c pariinl.h paricfg.h
	$(CCCMD) $(CCCDLFLAGS) $(DEFINE) $(MY_CC_PRE_TARGET)$@ -I $(PARI_DIR)/src/systems/os2 $(PARI_DIR)/src/systems/os2/os2.c
	Support code 'i' (this finishes support for 2.2.7).

	Won't work with 5.8.6 (ok with 5.8.5) [the cryterion of AV being
		empty changed: now it is AvFILLp() == -1; earlier AvFILLp()
		was not checked unless AvALLOC()].
	Document force_download option to Makefile.PL.
	T: make skipped test files emit the reason for skipping.
	Direct overloading of to-number was disabled: '0+' vs '+0'; actually,
		pari2num could not take more than 1 arg, so could not be used
		for overloading...
	passv() was used instead of pasv() in Net::Ftp interface in PariBuild.
	Likewise for <> vs <STDIN>.
	New option pari_tgz=PATH_TO_TAR_GZ to extract a local file and patch
		(if needed) the resulting directory tree.
	Now printing of DESTROY-debugging messages is controlled by macro
		RUN_IF_DEBUG_PARI.  From userland, use PARI_DEBUG(),
		PARI_DEBUG_set(), and environment variable MATHPARI_DEBUG.
	Add -w to test scripts.

	A memory leak on the PARI stack was possible in a rare situaton:
		if a PARI function returning a value which is not on stack
		(very few possibilities: gnil, gun etc.) is called when
		no Math::Pari temporary values are on stack, the GENs
		created for the function arguments would leak.
	Two new contributed debugging functions: dumpStack(), dumpHeap()
		(untested, undocumented).

	A patch to fix a broken 64-bit ploth test of 2.1.6.
	A patch to fix broken hiremainder overflow in port kernel (would not
	   work with -fno-common) of 2.1.6.
	On 64-bit platforms wrong set of tests was chosen, what would
	   result in false positives during tests.
	   Now test errors on 64-bit systems should be considered as
	   indicators of real failures.
	Skip 00_Pari.t:109 on 5.6.0 (bug in REx engine).
	Reasons of most common test errors mentioned in INSTALL.
	Move generation of the flag __HAS_NO_ASM__ to PariBuild.pm;
	   keep ASMINLINE in libPARI/Makefile.PL (since PariBuild.pm
	   knows little about $asmarch), but make it conditional on
	   $do_configure.  (Avoids warnings with Configure.)

	Mismatch between gpmalloc() and free() - possible reason for
		failure of 00_Pari.t:60.
	One branch in installPerlFunctionCV() could allow functions with
		unrecognized prototypes.
	Avoid "signed/unsigned mismatch" warnings in Pari.xs.
	SvPV_nolen() could be used even on older Perls...
	Remove all unused variables from Pari.xs found by M$ compilers and gcc.
	setprimelimit() would not return the old value, but new...
	Some XS functions which took GEN input and non-GEN output did not
		do necessary CLEANUP: ; some other which did not take GEN
		argument would start with oldavma=avma...
	interface5 (unused) would take 5 GENs, when it should have taken 4.
	Update PariBuild's process_sparc() and find_machine_architecture
		to 2.2.8's config/arch-osname.	(XXXX 64-bit disabled on non-alpha?)
	Update to new build method of 2.2.9+.
		XXXX config/Makefile.SH: see makeLVL1.SH logic to support GMP
	Some entry points disappeared in 2.2.*: pariK1, m_evallg, ...
		XXXX gshift3 now gone???
	Implement EXISTS method for Pari (fake) arrays (so one now can view
		PARI arrays in debugger too...
	Extensive update of the test suite to update to new numint/sumint
		flavors and extra spaces in the check-tests files.
	XXXX Temporarily skip nfisincl() - segfaults in 2.2.10...

	Extra include directory to pretend we are in $paridir/OFOO.
	Run funclist build process of GP/PARI...  (Modifies Pari directory...)
	Include forgotten patch for PERL_UNUSED_VAR

	paridir option to Makefile.PL was not documented
	With 2.2.10 (2005/1) intnum tests are WAY off:
	  Failed Test Stat Wstat Total Fail  Failed  List of Failed
	  t/intnum.t                50    9  18.00%  11 23-25 27 41-42 45 49
	Apparently, patches/diff_2.1.6_no-common is needed with 2.1.7 too.
	sparcv7 build was obsolete.
			=> overflow not defined
	The order of checks in find_machine_architecture() was wrong;
		instead of sparcv9 one would get sparcv7.
	Handling of private SvIOKp() flags was broken (the semantic changed
		long time ago).
	Better assember detection message.
	Advice how to debug problems with `overflow' and `hiremainder'
		not defined.
	Unless MATH_PARI_REPORT_CODES is set and TRUE, do not report ep
		codes mismatches (we do not use them now?).
	An attempt to avoid a memory leak when we are loaded from mod_perl
		(call reset_on_reload(1) to enable.  It kinda works,
		 but confuses perl_debug_mstats() - some memory problem).
	Make memory leak on restart down to about 425K (47577388 after 100).
	Remove the C fix for IOK of sv_true sv_false starting from perl5.6
		(tested with 5.00553 - needed to manually fix .c to avoid
		 a bug in xsubpp).
	Make tests work with 5.00553 too.
	(Finally!) add patch (to 2.1.7) to enable -g.
	Misprint in error message of interface_flexible_int().
	We were redirecting "_lex" as if lexcmp() had interface "lGG".
	loadPari() error message was failing for prototype errors
		in "directly linked" functions.
	Make generated tests start with "55_".
	Remove generated tests on "clean".

	Misprint in testing for 64-bitness would always load test results
		for 32-bit build.
	The patch for -no-common would break "port" build (in some situations?)
		remove from auto-patches, and add the note to INSTALL.
	Patches for -g and restart were omitted.

	Support Yet Another Scheme to Generate headers from function
		descriptors (for 2.2.11)
	Cast off `const' in s_type_name() (XXXX Do older xsubpp support const?)
	Support headers/paripriv.h (if present).
	Do not build function descriptions etc if they are already present.

 6 tests and 78 subtests skipped.

	Make getHeap() use PerlIO, and consistently use bytes for output.
	The patch for -no-common installed on Darwin only.
	Integer conversion was wrong between 2^31 and 2^32;
		tests on 64-bit might provide wrong positives???
		Provided another one if sizeof(long) < sizeof(IV).
	Change all occurences of 2002013 to 2002012
	User contributed: adds hppa support to the linux section of
		PariBuild.pm. Additionally, it adds
		a read flag check to the opening of /proc/cpuinfo, which on
		hardened linux boxes may fail.
	To pacify a warning, put ((void)0) instead of empty argument to a macro

	Test negative integer conversion too.
	Test ':int'.
	download_pari(), find_pari_dir(): skip versions 2.3.*
	force_download won't prompt.

	Better error message if ftp->quit fails; do it sooner.
	in uname: SunOS name 5.9 Generic_118558-26 sun4u sparc SUNW,Ultra-5_10
		allow for Generic* to be skipped (if 'sparc' present).
	Update find_machine_architecture() to 2.3.0 logic (so disable sparcv7).
	Append _64 to assembler architecture if needed.
	use strict in Makefile.PL.
	New function inline_headers2() in Math::BuildPari.
	Support 2.3.0 method of building pariinl.h, kernel.o, mpinl.o
		 - only in the case if no MakeLVL1.SH present.
	Link in plotnull.c if plotgnuplot.c is missing.
	Protect numeric constants in intnum too.
	One line in intnum test is wrapped.
	intnum.t would skip allocatemem().
	allocatemem() was not restoring the cached values of avma.

	Allow specification of 2.3.0 via pari_tgz.
	Add version to BuildPari.pm.
	Accomodate Darwin AS which tries to read from STDIN.
	Temporary disable skip if LVL1 is found (in 2.3.0); leads to
		Test returned status 0 (wstat 10, 0xa) on Darwin/port.
	On darwin, diagnoze arch via uname -p.  (SIGBUS during build)

	machine=port builds on 2.3.0 too (same failures).
	-DNO_GRAPHICS_PARI is not enough with 2.3.0; need -DNO_HIGHLEVEL_PARI,
		otherwise segfaults ???
	The branch with UV > ulong had a parens mismatch.

	Allow specification of 2.3.0 via pari_tgz, so manual override
		(for testing purposes only so far!) is easier.
	Add version to BuildPari.pm.
	Accomodate Darwin $AS which tries to read from STDIN.
	Temporary disable skip if LVL1 is found (in 2.3.0); leads to
		Test returned status 0 (wstat 10, 0xa) on Darwin/port.
	On darwin, diagnoze arch via uname -p.  (SIGBUS during build)
	More verbose hints on "Should I auto-download?".
	LWP download code would not binmode()...
	Test OLD subdirectory of GP/PARI ftp directory too.

	Accidentally, a version which would not use Net::FTP was released.
	Print manual download instructions of failure of autofetching too.

	Remove #error on LONG_LARGER_THAN_... (sp?).
	Warn on pitfalls of 2.3.*.
	On Solaris, support MakeLVL0.sh-style build too.

	Test suite was sub()ifying argument to sumnuminit().
	Test suite would not correctly sub()ify intnum() if limits had "()".
	Test suite calculated Pi Euler too early; Now only these fail

	Add warnings to the test suite for detection of #@_

	Attempt to support v5.10 (based on code contributed by Nicholas Clark)

  build_paricfg() takes a version argument
  write_paricfg(): likewise.
  Emit paricfg.h which supports GP/PARI v2.3.4.
  Remove the section on CPAN mirroring from README.
  INSTALL: Explain how to google when server is down.
	Apparently, patch by Nicholas Clark for narg was not mentioned in 
  Skip another subtest in ploth.t.

  Consider `intfuncinit' as requiring "unsane" precision of limits
	(bug in GP/PARI???).  Now all tests pass???

  Confusing variable name in Makefile.PL (===> $perl_int_size).
  AUTOMATED_TESTING taken into account when Makefile.PL asks the operator
  More clear self-documentation of Makefile.PL for manual download.
  Try to un-targz PARI archive also with Archive::Tar (may help with
	smoke testing on MSWin32).
  Convert patches diff_2.1.7_restart diff_2.1.7_-O to Unix line-endings
  multi-arch build; assembler not supported ==> auto machine=port.
  support v5.10 better: now take into account IVsize vs ptrsize
	(fixes "panic: PARI narg value not attached"; assumes int fits in void*
	 without checking XXXX)

  "More clear self-documentation of Makefile.PL for manual download" was busted
  Wrap slow access to stored IV via INT2PTR(), same for quick access.
  Auto-patch 2.1.7 for "Error: suffix or operands invalid for `div'"
  Auto-patch 2.1.6--7 for "kernel1.s:18: Error: alignment not a power of 2"
  Add missing empty lines to patches; clean traces of -p (on Solaris, patch
    is too stupid).
		*_restart fails?
  set DL_DFLT_NAME define in Makefile if option Configure is given.
  Change is_gnu_ass() to not_gnu_ass() in PariBuild.pm; return the
    usage message if present.
  assembler_flags_via(): as assembler_flags() with inverted second arg
	(may be a usage message from assembler);
  (DISABLED: causes segfaults on Solaris): try to guess for -K PIC for ASFLAGS.
  New test 000_load-problem.t reports build parameters (for smoke testing;
	taken from Numeric-Array).

  000_load-problem.t was busted...

  report more on environment when user does not answer `y'.
  report the response when listin of remote directory fails.

  Add a few "fake" Makefile macros to simplify remote debugging.
  Get log of command `ftp' if using Perl modules fails
	(if MATHPARI_USEFTP is TRUE, actually use the downloaded file).
  Patch for restart did not have leading "./" - problem with some `patch'es.

  PariBuild: return results of patching.
  Add a "fake" Makefile macro to report results of patching.
  "Just in case": change the leading component to "." in "diff_2.1.6_no-common".
  New argument to Makefile.PL: version23_ok=NUMBER (default 0).
  Add ftp-cmd to clean Makefile target.

  Change the default for $ok23 to 1.

  Add 5.005-new keywords to Makefile.PL.
  Consistently put space after -I in C include paths (needed???).
  Nicer output when debugging faulty LWP and Net::FTP.
  Make test engine look in */32/* directory too on 64-bit builds.
  Remove POD ornaments to make ABSTRACT_FROM work.

  Change the default for $ok23 to 1.

  Reword warning about slow intnum: only 75% longer than on PARI/GP.
	(overhead of the internal sub call in subtest 30 looks like 10x
	 overhead of an empty subroutine call).
  New advice that upgrade to 2.3.* may fix `overflow' and `highremainder'.
  Exchange order of initialization of PARI and of `functions_highlevel'
	with >= 2.3.0; allows installation of highlevel functions
	(in particular, install() and PostScript printing).
  New function have_graphics() (not exported).
  The test engine takes into account have_graphics().

  Change the default for $ok23 to 1.

  If AUTOMATED_TESTING, delete (bogus?) environment variable DISPLAY.
  If AUTOMATED_TESTING, report results of failing tests on STDERR.
  Make test suite report rough run times for successful subtests.

  Change the default for $ok23 to 1.

  Fix misprint and change die() to warn() on failure of $ftp->quit...
  Add some void's in Pari.xs.
  UNDONE (wrong): Protect init_graph() by NO_GRAPHICS_PARI (in restart code);
    include rect.h instead...
  sv2pari(),sv2parimat(): a stupid compiler might guess we don't return value...
  when patching, use && instead of ; in the shell command
  New function Math::PariBuild::patch_args()
  Math::PariBuild::patch_pari() supports option --binary, \ as directory
   separator in command processor.
  Make uname parser recognize i686-pc as ix86.
  Generator of function descriptors could try to regenerate existing file.
  nok_print() in Testout.pm was defined too late.

  Change the default for $ok23 to 1.

  Add (missing in 2.1.*) declaration for pari_init().
  Minor miscount in docs.

  Work around bug in XSUB.h (at least up to 5.11.2) with puts.
  Get GPDATADIR from gp, if present.
  Make self-documentation for switching to 2.3.* more explicit.
  kmx patch for mingw 32-bit Win-build:
	include windows.h (early!) in Pari.xs and highlvl.c
	enable assembler for this build
  x86_64 assembler detection after 2.2.7; thanks to Alexander Haeckel

  Change the default for $ok23 to 1.

 Similar (but slightly different) kmx patch to enable 2.3.5 build on mingw.

 p5p in its infinite wisdom removed (automatically generated) defines for PERL_POLLUTE...
	Now every extension needs to add them back by hand...

  GP/PARI in its infinite wisdom changed the structure of download directories.
  When downloading, we were not filtering v2.5 v2.7 etc against which we are not currently able to build.
  Support new format of $^O in Strawberry perl.
  On some installations of cygwin, Perl looks for cygperl5_1\d\.dll for linking.
  On some installations of cygwin, readable files are reported as not readable by stat(); workaround for ./typemap.
  Somehow, uname output on cygwin may have a trailing \cM at the end (stopped detection of assembler).
  Switch from using $Config{cpp} to $Config{cpprun} in libPARI/Makefile.PL [for 2.1.7] (cpp is missing in cygwin);
    - might have been the reason for problems with _overflow and _hiremainder on other platforms too!

  cygwin's tar generated 0-permissions for the distribution (no auto-workaround...).
  Document workarounds for isprime() with version 2.1.7 (in the BUGS section).

  Correct the documention about fraction of witnesses from >=0.25 to >=0.75.
  Define HAS_STAT and HAS_OPENDIR basing on $Config{i_sysstat} and $Config{i_dirent}.
  Correct spelling errors in POD and comments in Pari.pm (thanks to dsteinbrunner!).
  On AIX, do merge_822 separately in subdirectories (exceeds command line length otherwise).
  On >=2.3.0, reset had-newline-on-output to 1 at startup.  (Saves one spurious NL)
  New patch: diff_2.3.5_stderr_clobber
  New test: 01_no_extra_newlines.t
  Allow download not only via FTP, but also through HTTP.
  In presence of PERL5_CPAN_IS_RUNNING, assume that NO ANSWER on prompt is agreement.
	(It looks like cygwin and MSWin32 automated-testing environment do not have
  Do not auto-download on 64-bit builds of MSWin32.

  Too long version name was a misprint.
  Pay attention to PERL_EXTUTILS_AUTOINSTALL when interpreting empty answers to prompt (probably an overkill).
     (disable this abomination by PERL_MATHPARI_TRUST_MANUAL)
     (to see why this may be needed: http://www.cpantesters.org/cpan/report/a5d65ec6-6bf3-1014-87a8-67ba45601f20)
  Report bytes in the answer for prompt.
  Separate into separate subroutines inspecting versions available for download from the actual download.
  Change the logic of fallback Net::FTP --> LWP: before, if Net::FTP fails in retrieving the directory listing;
    now: if this happens, or if it fails to retrieve the file (how can it happen?! see http://www.cpantesters.org/cpan/report/e7f9d5a7-6bfa-1014-9d0f-1948c9c86cae)
  __wrap_PARI_macro:	new function (not exported)
  parse_as_gp:		new function (exported by default)
  More verbose error message for "Cannot load a Pari macro".

  A night of sleep fixed problems of parse_of_gp with the operator \ and empty lines.
     (test suite updated)
  Actually, mingw was not ready for HAVE_OPENDIR.
  Store which patches were applied in $dir/.perl.patches.
  Report which patches were not applied.
  Export patches_for() from BuildPari.
  pari_tgz build option was broken (by LWP-after-NFTP support code — which, apparently, did not help with timeouts).
  Ignore 0-size "downloaded" files.
