For anyone interested in OpenMP stuff.

Attached is a small project that shows how to use OpenMP with the CRT qsort.

When OPENMPTEST is defined as 0 no OpenMP stuff is used, when 1, it is used.

timings are 0 > 3285ms, 1 > 1969ms.

That's strange. I can't say what's wrong.

EDIT: Are you using the latest version of PellesC?
