Some libiberty functions, such as getopt, was moved to GNU, BSD and
other C libraries. Many (like some x* ones) are very simple. Please try
a patch (see my another message within "Removing libiberty" topic) which
utilizes many functions from standard libc, shipped with build OS.

Another reason to use libc native to OS, is optimization.

Anyway, as for me, GNULIB is better way than have libiberty in tree.
Thanks for pointing it out!

Does GNULIB provides the shared library (.so)? If so, there is would no
need to create extra directories in GNATS tree.
