fwiw:

I've done a few quick tests on a lib i'm working on (a Windows DLL built
with VC9).

The lib has 27 public headers which currently contain both normal include
guards and #pragma once, and takes ~45 seconds to compile+link. I've tried
building it with just include guards, and with just #pragma once, and theres
no noticable difference between the build times.
