Thanks Volker. I'll give it a try. 

I'm still interested in the right way to really set up these flags
though. I was looking at some of the online docs and found stuff like
this in some emails:

"I'm compiling currently with -mfpmath=387 -msse -mcpu=pentium3
-march=pentium3 and gcc 3.1.1-4 from the very latest experimental
cygwin distribution."

Obviously I'm not intested in cygwin, etc., but when I saw -msse it
made me wonder if I was supposed to change my CFLAGS line from

CFLAGS="-O2 -march=pentium4 -pipe -fomit-frame-pointer"

to 

CFLAGS="-O2 -march=pentium4 -pipe -fomit-frame-pointer -mmx -msse -msse2"

I understand that the USE flags control what options are built into a
pachage, but in the case of CPU flags do they also control the
compiler flags that are used to build the package? Not being a
programmer this is one part I'm confused about.

Thanks,
Mark
