CFLAGS is a standard Makefile setting, but not all programs use it.

This how I use it.
export CFLAGS="compile options" ; ./configure --prefix=/usr ; make -e

export -n CFLAGS removes it from the shell environment.

gcc-2.9.5 uses the Bootstraps option to compile itself in three 
stages. Comparing itself too itself along the way. Hopefully this
ensures a good build.
