[PATCH xfs] Fix CFLAGS and LDFLAGS for Cygwin/MinGW

[Yaakov (Cygwin/X)]

From: Yaakov Selkowitz <yselkowitz at users.sourceforge.net>

As in xserver, FD_SETSIZE must be overridden due to a too-low default,
and symbols must be exported for compatibility with the shared libXfont
stub handling on these platforms.
