Hmm.. -fexpensive-optimizations are included in -O2. -mpentiumpro is the same
as -march=pentiumpro and -march=pentiumpro implies -mcpu=pentiumpro.
-fomit-frame-pointer will kill ALL crash-backtraces.
I use:
CFLAGS='-pipe -march=i686 -ffast-math -finline-functions' \
CXXFLAGS='-pipe -march=i686 -ffast-math -finline-functions' \
../configure --disable-debug --enable-warnings \
--enable-fast-malloc --enable-final
