I have a question in regards to pentium or higher optimization,
source, and rpm. Is there a means to make the default rpm
--rebuild command use better than -02 -m486, etc? I would
like a situation where I enter "rpm --rebuild x.src.rpm" and
have the optimizations run to -03 -mpentiumpro -march=i686, etc.
Barring that, is there a means of driving this from the command
line (perhaps I could create a script that would do this
for me whenever I enter rpm --rebuild)? Or must I dig into
a make file or two, config file or two, etc, in the source to
do this? Of course, this defeats the ability to use rpm
--rebuild, as far as I see thus far since it would require
rpm -Uvh x.src.rpm to un-rpm and install the source, then have
to run make, etc from the command line.

Usually, I'm using:
-O6 -fomit-frame-pointer -fno-exceptions -fno-rtti -fno-check-new
-ffast-math -mpentiumpro -march=i686 -pipe -s -fexpensive-optimization
s
If you think size is more important than speed, you might want to
replace
-O6 with -O2. Also, -O6 is rather experimental, so if it breaks
something,
you might be able to fix it by replacing -O6 with -O3. (I'm running
the
i686 -O6 glibc here without problems though).
