Then you were using GCC 2.7.2 in FreeBSD 3.3 -- a very different animal
than 2.95.2.

WHY!?!?!? Just what the heck do you think you're achieving with -O3 plus
all those things? Have you *ever* profiled anything you're compiling
with these options? Note that -O3 is not necessarily faster code than -O.
This seems Yet Another "I'm macho" compiler flags instance.
Please correct me if I'm wrong.
