where to find the default cflags in FC4 ?

Hello, all

My FC4 install on a Pentium3 defaults to " -mtune=pentium4 " for my
gcc(32) flags (among other unwanted ones)

Does anyone know /where/ the CFLAGS defaults are set on the system?

This misconfiguration is crippling/fatal to compiling.

I have tried setting my own CFLAGS, but some ./configure scripts
combine the $CFLAGS contents with something else, the origin of which i
can't determine.

TIA
andrew
