May I assume this is good for the SPARCclassic, which is also sun4m?

Actually, I build almost everything from the tarballs.  In general do
these architecture optimizations go into CFLAGS, or should I define CC
with the options included?  (Or, even more drastic, should I be building
gcc somehow so that it uses these optimizations by default?)

Thanks a million.
