Hi!

This sounds rather interesting for me since I am working with number crunching
applications on an Athlon, too. I made some tests with egcs-1.1.2 and
pgcc-2.95.3. It turned out that (besides other switches) -march=486 on egcs
gave best performance. So my questions are: Which switches do you use for this
increase in performance for (double precision) floating point arithmetic? Where
can I find Agcc? I have some short (1000 lines) but timecritical routines.

Thanks!

Michael
