Thanks for the replies. I don't understand these optimizations flags too 
well. But from these posts I gather the optimization flags work well for 
other processors except pentium4's. Is this true or is there some other 
problem that's causing these errors?

How do I correct this problem? Do I start looking on the gcc website for 
bugs and patches?

If I had to choose between compiling xfree86, xscreensaver and mozilla 
with gcc3 and lower optimization flags or with gcc2, which would be better?

I do agree that xfree86 should not be changed to back gcc2 if the 
majority of users compile fine with gcc3.

Regards, Duane.
