They will all build, but your improvement will vary a lot, from -5% to +50% in
my experience.   This is essentially what the Mandrake distribution has done
with Redhat.    It's very much up to the programmer.   You could try all these
options too:
optflags: i586 -O2 -mpentium -mcpu=pentium -march=pentium -fomit-frame-pointer
-fno-exceptions -fno-rtti -pipe -s -ffast-math -mieee-fp
-fexpensive-optimizations -malign-loops=2 -malign-jumps=2 -malign-functions=2
optflags: i686 -O3 -mpentiumpro -mcpu=pentiumpro -march=pentiumpro
-malign-loops=2 -malign-jumps=2 -malign-functions=4 -fomit-frame-pointer
-fno-exceptions -fno-rtti -pipe -s -ffast-math -fexpensive-optimizations
