	  parentheses (rejected by GNU as).
	* lib/Asm/X86.pm (_add_percent, _remove_duplicates, _nopluses): removed
	  "my sub" and added an underscore to the name to mark the subroutines
	  as private and still make POD coverage tests skip them.

	  is_reg16_intel, is_reg16_att, is_segreg_intel, is_segreg_att,

	  Added functions checking if the given string represents a register
	   in AT&T syntax. Renamed the previous functions with an "_intel"

	  Added AT&T-style instruction mnemonic array.
	  Added functions for checking if a given string represents a
	   valid 16-/32-/64-bit addressing mode in AT&T syntax.
	   Renamed the previous functions with an "_intel" suffix and the
	   new functions with an "_att" suffix. Old functions (the ones
	   with no suffixes) now check for either Intel or AT&T syntax,
	   so they remain valid.
	  Changed Intel syntax addressing analysis to check if the whole given
	   string is correct (using ^ and $ in regular expressions).
	  Added functions to convert an addressing mode or instruction (with
	   all its operands) between AT&T and Intel syntaxes.
	  Added functions to convert an instruction or memory addressing mode
	   between Intel and AT&T syntaxes.
	  Converted subroutine names to prototypes.
	  Added the compile-once flag where applicable.
	  Added PRIVATE to documentation of private non-exported subroutines.

2008-03-29	Bogdan Drozdowski <bogdro \at\ cpan . org>

	   form [ebx+r10d] were not recognised properly.
	  Added the "SUPPORT AND DOCUMENTATION" section from the README file
	   to the module.

	  Added a list of segment registers and a function for checking
	   if a given string represents a segment register.
	  Added functions for checking if a given string represents a
	   valid 16-/32-/64-bit addressing mode.
	  Added a list of FPU registers and a function for checking
	   if a given string represents an FPU register.

2008-03-08	Bogdan Drozdowski <bogdro \at\ cpan . org>

	* Version 0.01:
	  Includes all known by FASM instruction mnemonics and registers.
	  Includes functions that check if a given string is a register
	  (any type or explicit: 8-, 16-, 32-, 64-bit or multimedia) and
	  functions that check if a given string is a mnemonic.
