Build-time optimizations

[Nikolay Datchev]

Hello list,

How can i add additional compiler flags to the and g++/c++ compilers to
build Xorg with some custom flags?
Something like CFLAGS and CXXFLAGS before ./configure in most software.

I want to build the 6.8.0 release for my pc (k6-3), does it worths to
build from scratch to use mmx 3dnow and -march ? Currently, i'm using the
pre-build 6.7.0 package of slackware-current (i486 optimized).

Thanks.
