Always wanted to know what -pipe did; neato! No I didn't have it in
there.. I don't really want to use the suggested -O2 -m486 however, so I
think I'll add -pipe. I don't have the time to do another make world to
compare however..  I've got 32 MB or RAM - is this considered enough?
SCSI - of course: NCR 810, but the disk (CONNER CFP1060S 1.05GB 2035) is
rather slow. CPU is a 150MHz pentium pro, 128-bit interleaved RAM (STREAM
says about 94MB/s..).

Any idea how much faster -pipe generally speeds up the compilation? I'm
assuming I might need more RAM for the PIPES to talk though.. I'll be up
to 48MB soon, then I'll be happy  :-)

Thanks,
-Mark
