Any advantages to compile from scratch for 2004.0 release?

[darkcore]

Hi all,
Previous posts suggested that current GCC doesn't support much optimization flag for AMD64 architecture and we should only use '-O2 -pipe' for CFLAGS. Therefore, I felt I might just want to install all precompiled GRP packages, since there's nothing much I can tweak for performance. Are there any advantages to compile packages from scratch for 2004.0 release as they are compiled in same CFLAGS? The only advantage I can think of is to test drive my new AMD64 machine to see how fast is it.

Thanks,
Oscar

USE Flags might change the things that are supported by the packages if compiled from source ...
