I've uploaded a new patch to Sourceforge in response to feedback:
* I purged all // comments and fixed all > 80 characters added by my
patch, as per Neil Norwitz.
* I added a definition of max() for those who don't already have one,
as per [EMAIL PROTECTED]
It now compiles cleanly on Linux again without modification; sorry for
not checking that since the original patch.
I've also uploaded my hacked-together benchmark script, for all that's
worth.
That patch tracker page again:

I'll do that next time. In the meantime, I've also uploaded a zip file
containing the results of my benchmarking, including the stdout from the
run and the "-f" file which contains the pickled output. So you can
examine my results yourself, including doing analysis on the pickled
data if you like.

The machine is dual-core, and was quiescent at the time. XP's scheduler
is hopefully good enough to just leave the process running on one core.
I ran the benchmarks just once on my Linux 2.6 machine; it's a dual-CPU
P3 933EB (or maybe just 866EB, I forget). It's faster overall there
too, by 1.9% (minimum run-time). The two tests I expected to be faster
("ConcatStrings" and "CreateStringsWithConcat") were consistently much
faster; beyond that the results don't particularly resemble the results
from my XP machine. (I uploaded those .txt and .pickle files too.)
The mystery overall speedup continues, not that I find it unwelcome. :)

I sure was. And I used stringbench.py downloaded from here:
