With the very latest ORBit from CVS I keep having this problem. I still
don't understand in what way AM() and PM() are messing things up. After
defining these two macros to be empty, gnome applications are starting
up again. But I still don't understand what's wrong with my system
(Linux 2.0.36, glibc-2.06) and I'm obviously the only person
getting this. Any ideas?
