Weird... on my cygwin setup, config.h has a line saying "#define
HAVE_UNISTD_H 1"

This one does not give problems to me.

I attached the GCC dumpspecs output for GCC under cygwin. I have no clue
here.

Anyway, my configuration is unable to build tethereal, for several reasons,
the most peculiar one being the lack of an "-I." in the compile line, and
the more tricky ones the compilation of tethereal[.exe] before the
dissectors and other dependent code have been compiled. I use the following
tools:
gcc: 3.3.1 (cygming special)
libtool: ltmain.sh (GNU libtool) 1.5 (1.1220.2.1 2003/04/14 22:48:00)
libtoolize: libtoolize (GNU libtool) 1.5
aclocal: aclocal (GNU automake) 1.7.6
automake: automake (GNU automake) 1.7.6
autoconf: autoconf (GNU Autoconf) 2.57
autoheader: autoheader (GNU Autoconf) 2.57
autom4te: autom4te (GNU Autoconf) 2.57
