ok.

After reading the FAQ for cygwin, I found that the library switches must
appear at the end of the command line. Cygwin also needed the "-mwindows"
switch turned on.  So, I moved the "-lFOX" switch to the end and added
"-mwindows" and here's the results after running it: 

=====OUTPUT=====
$ gcc -o x.exe -O2 -g -I/usr/include -L/usr/lib  -mwindows x.c -lFOX
cc1: warning: changing search order for system directory "/usr/include"
cc1: warning:   as it has already been specified as a non-system directory
/usr/lib/libFOX.a(fxutils.o.b)(.eh_frame+0x11):fxutils.cpp: undefined 
reference to `___gxx_personality_v0'
collect2: ld returned 1 exit status
================ 

Even though gcc did not work, g++ seems to work, keep reading...

After moving the "-lFOX" switch to the end and adding "-mwindows" it seems
to compile with g++ 

=====OUTPUT=====
$ g++ -o x.exe -O2 -g -I/usr/include -L/usr/lib  -mwindows x.cpp -lFOX
cc1plus: warning: changing search order for system directory "/usr/include"
cc1plus: warning:   as it has already been specified as a non-system 
directory
$ if [ `./x.exe` ]; then echo "YES"; else echo "NO"; fi
NO
$ # it returns zero which is the expected behaviour

$ g++ --version
g++ (GCC) 3.2 20020818 (prerelease)

I used cygwin's setup.exe and this is the default version that is being 
installed, gcc 2.95 is still available though. 

A side note, cygwin's latest autoconf is only versin 2.53b and your 
aclocal.m4 requires 2.54.  This seems to be merely an inconvenience as
I was able to change the version to 2.53b and run autoconf just fine.
