 What? is gcc 2.7.3 out? or is this just a typo? anyway, next release should
really have pentium optimization. And also bugs fixed. Like C++ packing. And
I also noticed, that __attribute__((cdecl)) dicards __attribute__((regparm)).
This sucks. Those two combined could make better code. Yeah, and the strenght
reduction fixed as well. Whoops... This is plain off-topic. Sorry... What's
the e-mail address to send stuff like this? gcc-bugs@... or smth?. Is it in
the FAQ, i don't remember?.. Again, sorry for off topic, just felt like saying
this... :)

P.S. and future gcc should also support instruction re-ordering to avoid
     stalls. For now it says: option not supported for the specified target.
