Exactly.  Adding gettext support to groff would be nice, but until now
it hasn't happened.

The less dependencies, the better IMHO.  Most modules have gettext for
internationalized messages only, right?  I think it is better to leave
it to the application whether gettext support is wanted or not.

You mean such a code could be added to getopt.c, right?

To be honest, I consider this not elegant.  Distributing a header file
just for the sake of satisfying a dependency looks like a hack.

I really prefer a `real' fix, this is, adding the above code to the
affected source files.  For me, it looks `more right'.
