To be honest, Dimi and I did just that last week when modifying
glib2's configure script to cross-compile.  The native case was
doing a horrible kludge to avoid including the normal Posix include files 
to get POLLIN; in the cross-compile case only, we replaced that
with something simple that assumes Posix include files.
It's a sneaky way of ripping out cruft: do it only in the
case the normal development team doesn't care about, to maximize
the chances the patch will be accepted :-)

Say, does that mean ACE has a working autoconf-generated configure
script now, or are you describing an unfinished project?

Thanks,
