gcc-3.0 update

[Jeff Bailey <jbailey@nisa.net>]

Last update for the evening:

I think I've found the problem.  ltcf-cxx.sh disables shared libraries
for c++ unless it's been specifically told that it's possible.  I'm
going to try this.  If one of you gcc-hackers can tell me if this is
reasonable, I'd appreciate it before I submit this fix.  I'm going to
try a compile tonight while I sleep.
