solved: X compile fails for missing (internal?) symbols

[Dick Repasky <rrepasky at lack dot ucs dot indiana dot edu>]

The original problem report is 
http://cygwin.com/ml/cygwin-xfree/2007-04/msg00004.html.

After that problem was solved, two others emerged. This message documents 
fixes for all three.

1) As posted earlier

xftpat.o:xftpat.c:(.text+0x3c2): undefined reference to `_FcPatternInsertElt'
xftpat.o:xftpat.c:(.text+0x3ce): undefined reference to `_FcPatternFindElt'

   The symbol names have changed as documented in
   http://www.mail-archive.com/devel@xfree86.org/msg07963.html. That post
   contains two alternative patches, one that patches both xftint.h and
   xftpat.c and a second patch that changes only xftint.h with defines.
   The former patch worked for me, but the latter "even quicker" patch did
   not work for me.

2) Bad includes in lib/font/FreeType/ftfuncs.c
   Briefly, a #define symbol that specified a file to be included in
   a #include was not defined, and hence, the file to be included could
   not be found.

   The fix is dirty. Place the line

   #define HasFreetype2 NO

   in config/cf/host.def. I realize that X is supposed to be built using
   the installed cygwin freetype package, but I could not figure out
   how to get X to use the cygwin package.  By forcing HasFreetype2 to NO,
   X builds a copy of the library for itself. Maybe someone else knows
   or can figure out a better solution.

3) #include png.h fails.

   libpng is not specified as a dependency
   in http://x.cygwin.com/docs/cg/prog-build-native.html, but is is
   needed to build X.

With those fixes X compiled for me.

Your mileage may vary,

Dick
