Unfortunately, I only have the free Visual C++ 2008 Express, which
doesn't include the profiler.

Ok, I tried with Very Sleepy, but I don't think it's accurate enough
with its sampling (and I don't fully understand the output). The
results seem to vary wildly with every run. FWIW, here is one of the
"captures" in attachment, in the native sleepy format (only way to
export the data).

(Shiny seems to work only with C++, not with C. AMD CodeAnalyst is for
AMD processors only, not useful to me. And I don't want to register on
the AQTime website to get a trial of 14 days (or pay $599))

If anyone has any more suggestions, short of installing a Linux
distribution and trying a linux profiler ...
