Re: [Valgrind-users] Problems with XFree-4.3

Just a warning, but march=pentium 4 is broken in gcc.

I've had everything from sound problems to floating point conversion problems 
due to it...  If you have anything compiled with march=pentium4 I'd 
definately recommend downgrading to at least march=pentium3 since pentium4 
has a floating point conversion bug that's really nasty.
