bug#13112: 24.2.90; The cygw32 build should disable X11

[Ken Brown <kbrown@cornell.edu>]

The cygw32 build of emacs tries to use many X11 features if the builder
has the appropriate development packages installed.  For example,
HAVE_GSETTINGS and HAVE_GCONF will be defined.  This causes serious
problems, as detailed starting at
