Try -mcpu=ultrasparc. gcc generates sparc V7 code by default (no integer
mul/div instructions, so call to library routines are divided)

Also try Forte / WorkShop (Sun's own compiler). It usually generates
better code, sometimes by a substantial amount (although I would guess that
the difference for Python isn't that big)

(of course sparcs cannot really compete with modern x86 cpus on performance
nowadays, unfortunately)
