That's because the Makefile generated by the configure script *ignores*
X_LIBS.  You'll need to force -lX11 into the link line of every affected
Makefile. if you want it to link against this library.  This is a problem
with the app's configure script, not Cygwin.  You should report this to
the maintainers.
