	* configure.ac: Search for ISO/ANSI definitions of uint32_t in
	  stdint.h _and_ inttypes.h before POSIX u_int32_t in sys/types.h
	  as some systems have sys/types.h without the definition.
	  Eventually we need to code a test that the expected UINT32
	  definition exists in the header we select so order does not
	  matter.

    * lib/dgif_lib.c, lib/gif_lib_private.h, lib/gif_err.c:
      - When Compiling for Game Boy Advance, file functions are not needed so
        exclude DGifOpenFileName(), DGifOpenFileHandle(), DGifSlurp(), and
        PrintGifError().
      - On Game Boy Advance we need to reduce memory usage.  Change values to
        short int where appropriate.
    * lib/gif_lib.h:
      - Handle te GBA changes by defining GifPrefixType and GifWord to int
        unless compiling on GBA.  Then use unsigned short and short
        respectively.
      - Fix a problem with the API on _WIN32.  DrawText conflicts with the
        Windows API.  Call it DrawGifText instead.

      - EGifPutComment(): reimplemented using EGifPutExtensionFirst, Next, and
        Last so that it won't break on unusually long comments.
      - EGifPutExtension{First,Next,Last}: Changed fwrites to WRITE so any
        user defined write function will get called properly.
      - EGifPutExtensionLast: if the Extension block is empty (Zero length)
        then don't attempt to output a last extension block, just output the 
        block terminator.
      - EGifPutExtension: Comment that this function does not work when there
        are multiple subblocks in an Extension block.  Use the functions
        EGifPutExtension{First,Next,Last} instead.
      - EGifSpew: Reimplement to use EGifPutExtension{First,Next,Last} so we
        don't output broken GIFs when there are multiple sub-blocks on an
        extension.
    * lib/Makefile.am: Bump version to 4.1.3.

2004-02-22 Toshio Kuratomi <[e-mail]> - r57    
    Merge changes to the code from branch indent-audit r55
    * README: MakeExtension deprecation note.
    * TODO: Bunch of things I need to fix or check that I saw while doing the
      indentation of the code.
    * lib/getarg.h: indent changes
    * lib/dgif_lib.c: indent changes
      - Move stdlib.h out of #ifdef's as it's included on all platforms.
      - Add checks to be sure malloc and MakeMapObject succeed.
    * lib/quantize.c: indent changes
      - Move stdlib.h out of #ifdef's as it's included on all platforms.
      - _GifError already pulled in through gif_lib_private.h.  Remove decl.
      - Make Count in NewColorMapType be unsigned.
      - Separated mallocs from conditionals in a few places.  Easier reading.
    * lib/gifalloc.c: indent changes
      - Added four FIXME's where I think the code might not be doing what we
        want.  Need to do more research to figure out.
      - Add note to MakeExtension that I think it needs to be deprecated.
      - Separated mallocs from conditionals in a few places.  Easier reading.
      - FreeLastSavedImage: New private function to free the last image in a
        GifFile structure.  Used to back out when unable to completely
        allocate a new SavedImage structure.
      - check for NULL values before deallocating in Free* functions and make
        sure all Free* functions set the pointer to NULL after they deallocate
        the memory.
    * lib/egif_lib.c: indent changes
      - EGifPutScreenDesc: If we have no colormap, output a default value for
	its size instead of trying to reference its unallocated BitsPerPixel
	field. (Fixes bug noted in r46)
    * lib/gif_lib.h: indent changes
      - Condense the #else #if VARARGS to #elif VARARGS check.
    * lib/qprintf.c: indent changes
      - Condense the #else #if VARARGS to #elif VARARGS check.
    * lib/dev2gif.c: indent changes

    * lib/gif_font.c: indent changes
    * lib/gif_err.c: indent changes
    
2004-02-22 Toshio Kuratomi <[e-mail]> - r56    
    * lib/Makefile.am, util/Makefile.am: Add -Wall to the compilation flags so
      we can keep the code from acquiring too much bad style.
    
2004-02-20 Toshio Kuratomi <[e-mail]> - r46    
    * egif_lib.c: Note for a bug fix (Can wait until after indent because
      there's no patch.)
    * gif_lib.h, dev2gif.c: Change int type to explicit long type in
      DumpScreen2Gif.
    * util/gifinto.c: Give the fprintf back its %d format.
      GifFile->ImageCount is used as the Image number.
    
2004-02-20 Toshio Kuratomi <[e-mail]> - r45    
    * README: add varargs to the deprecation list

2004-02-20 Toshio Kuratomi <[e-mail]> - r44    
    * test-unx: Quote the program names.
    * lib/dgif_lib.c:
      - Make sure memory was allocated for the colormap
      - Some reformatting of code but no syntactic changes.
    * lib/gif_lib.h:
      - C++ extern "C" fix
      - Fix typo with EGifOpen
    * lib/qprintf.c, lib/getarg.c: Update the varargs code.  Some users reported
      that not all systems can handle the hybridized varargs parameter lists
      we had.  Need to use old-style declarations instead.
    
2004-02-20 Toshio Kuratomi <[e-mail]> - r43    
    * NEWS: Note bugfixes and deprecations
    * README: Deprecation list is now being compiled in this file.
    * TODO: Notes about interlace bug, -Wall status, merging of old bug status
    
2004-02-19 Toshio Kuratomi <[e-mail]> - r42    
    * Makefile.am: Disable testing for now because gif2x11 is broken so none
      of the tests _appear_ to complete successfully.
    
2004-02-19 Toshio Kuratomi <[e-mail]> - r38    
    Merge -Wall fixes from branches/Wall-audit r29
    * configure.ac:
      - Make the stdarg vs varargs check simpler by relying on
        AC_CHECK_HEADERS() magic.
      - Check for unistd.h
    * dgif_lib.c, gif_lib.h, egif_lib.c, gifalloc.c, quantize.c, dev2gif.c,
      getarg.c, gif_lib_private.h, gif_font.c gif_err.c, gifinto.c, icon2gif.c,
      raw2gif.c, gifcolor.c, gifasm.c, gif2epsn.c, gif2iris.c, gifrotat.c,

      gifclrmp.c, giffiltr.c, giftext.c, gifinfo.c, rgb2gif.c, gif2rgb.c, gif2ps.c
      - Changes to get rid of -Wall compile warnings.
        + Casting of types
        + New header includes for unistd.h and fcntl.h
        + Explicit declaration of many types to unsigned
        + Removed unused variables and functions
        + Removed VersionStr from every library file.  Instead include it via
          gif_lib_private.h
    * gif_lib.h, gif_lib_private.h: Moved the VersionStr into gif_lib_private.h
      and made it a #define instead of a static char *.
