Thanks very much for the tip, and to the many other helpful replies in
this thread. 

I didn't even know I had gprof on my computer- but I do. Now, how do I
use it? running 

gprof example.exe

produces, in brief, a "gmon.out not found." Don't know what gmon.out
is/was.

Anyway, I looked a bit on DJ's site, no find yet. will look some more.
Any quick tips as to how to run it and how to study what it gives
back?
