I tested with gcc 2.95, 3.3 and 4.0 on FreeBSD 4.10 (only machine I had available with those gcc versions) and both 2.95 and 4.0 show a 10-20% speedup of your testcase in 2.5 compared to 2.4. 3.3 showed a 10% slowdown or so.

Does 4.0 show a general slowdown on your test machines? I saw a drop of average Pystones from 44000 to 40000 and from 42000 to 39000 on my boxes switching from GCC 3.4.6 to 4.1.1.
