From Joerg Mayer:
In the "configure.in" files, add
-D_U_="__attribute__((unused))"
to CFLAGS if we're using GCC, and add
-D_U_=""
otherwise, so _U_ can be used to mark arguments as unused.
Add -D_U_="" arguments to the Makefile.nmake files as well, so _U_ works
with Microsoft Visual C++ as well.
Add comments and RCS IDs to the Makefile.nmake files that don't already
have them.
