Yeah, I'm not so sure about this.  I don't know offhand what else the
DEBUGGING define will do to Perl.  That's why I just changed the
installed Config.pm.  It might be worth posting something on one of
the Perl newsgroups.

Anyway, most Perl extensions are small enough that the 8k GOT limit
doesn't bite you - Gtk/Perl is a very large extension, and it's the only
one I've seen which hits the limit.

Now that you've got it built, I'd say you can safely quit while you're
ahead - just bear in mind that the next time you build a new version of
Gtk/Perl, you'll have to remember to modify the Makefile again.
