    * createirepfrombinary.cc: Removed trailing whitespace.
    * dwarfgen.cc: Added option --add-implicit-const to
      create an object with DW_FORM_implicit_const.
    * general.h: Added bool addimplicitconst flag for the
      new option.
    * irepattrtodbg.cc: For DW_FORM_implicit_const
      add a call to new libdwarf function
      dwarf_add_AT_implicit_const().
    * ireptodbg.cc: New static function addImplicitConstItem()
      deals with replacing parts of existing variables
      with DW_FORM_implicit_const when the new option used.
2018-10-03 David Anderson
    * dwarfgen.cc: Now uses dwarf_init_b() instead
      of the original dwarf_init().
2018-09-21 David Anderson
    * dwarfgen.cc: S_IRUSR was defined incorrectly
      (when not provided by system headers). Fixed.
    * CMakeLists.txt: Updated headers list to include all 
      the local headers.
    * Makefile.am: Ensured config.h.in.cmake and
      dwarfgen.1 get into releases.
2018-09-11 David Anderson
    * ireptodbg.cc: Removed pointless comment.
2018-08-02 David Anderson
    * irepattrtodbg.cc: Fixed a typo and removed/#if 0
      some debugging code

      to them.
2018-07-31 David Anderson
    * Makefile.am: Moved ChangeLog etc out of /usr/share
      but have them in the distribution. Now make install
      puts nothing of dwarfgen in /usr/local/share.
2018-07-31 David Anderson
    * createirepfrombinary.cc: Delete blank line.
    * dwarfgen.cc: Adding new option --force-empty-dnames
      to force out .debug_names section (even if empty).
      Added dwarf_transform_to_disk_form_a() which
      does the same as dwarf_transform_to_disk_form() but
      has a status as the return value and returns its
      value via a pointer arg.
    * irepattrtodbg.cc: Removing some useless whitespace.
2018-07-24 David Anderson
    * dwarfgen.cc: CallbackFunc() was awkwardly declared
      (now more sensibly declared as static function, 
      still extern "C" as it is called from C (libdwarf)) 
      ErrorHandler() was unused (now deleted).
2018-07-23 David Anderson
    * createirepformfrombinary.cc: Removed unused local variable.
      #define UNUSEDARG appropriately
    * createirepfrombinary.cc: Removed extra ';'.
      #define UNUSEDARG appropriately
      mark static functions as such to avoid warnings.
      Mark arguments UNUSEDARG where appropriate.
      Test the correct libdwarf return value.
      Delete unused local variables.
    * dwarfgen.cc: Declared functions for C callbacks
      as extern C.
      #define UNUSEDARG appropriately
    * general.h: Reformat the header comments to avoid
      too-long lines.
      Delete duplicative comments.
    * irepattrtodbg.cc: Fixed reinterpret casts to be
      the correct type which made the typedef myintptrt
      unused (and now deleted).
      #define UNUSEDARG appropriately
      Mark arguments UNUSEDARG where appropriate.
    * irepdie.h, irepform.h: Mark arguments 
      UNUSEDARG where appropriate.
    * ireptodbg.cc:Fixed reinterpret casts to be
      the correct type, fixing signed/unsigned
      comparison warnings.  Removed some unused
      local variables. Fixed a couple declarations
      to avoid signed/unsigned comparison warnings.
      #define UNUSEDARG appropriately
      Mark arguments UNUSEDARG where appropriate.
2018-07-22 David Anderson
    * dwarfgen.cc: The relocations processing was assuming
      alignment of 32bit and 64bit values. Now no longer
      makes that incorrect assumption.
2018-07-16 David Anderson
    * createirepformfrombinary.cc: Refines ifdef of HAVE_STDAFX_H
    * createirepfrombinary.cc: Refines ifdef of HAVE_STDAFX_H
      Delete unused local variable.
    * dwarfgen.cc: Refines ifdef of HAVE_STDAFX_H.
      Changes certain function_argument names to avoid
      shadowing a global. For example, elf -> elf_w
    * general.h: Remove pointless trailing ; ending IToHex()
    * irepattrtodbg.cc: Refines ifdef of HAVE_STDAFX_H.
      Rename local vars to avoid shadowing. Example: form -> form_a
    * ireptodbg.cc: Refines ifdef of HAVE_STDAFX_H.
      Rename local vars to avoid shadowing. Example: error -> lerror

    * Makefile.am: New, used by autotools to create configure.
    * configure.ac, Makefile.in, config.h.in: Deleted.
2018-06-19  David Anderson
     * dwarfgen.cc: Now it's intended to build for Linux
       or Windows and get usable file open modes automatically.
2018-06-14  David Anderson
     * Makefile.in
     * config.h.in,configure.ac
       Removed unnecessary defines and checks.
     * configure: Regenerated

     * configure.ac: New option --enable-elf-open
       setting HAVE_ELF_OPEN
     * config.h.in: HAVE_ELF_OPEN
     * configure.ac: Regenerated.
     * dwarfgen.cc.c: Now uses open() unless HAVE_ELF_OPEN
       is explicitly set.

     * dwarfdump.c:  Change WIN32 to _WIN32.
2018-06-05  David Anderson
