I would appreciate any feedback towards a possible patch. I am currently running the boost thread tests and hoping that they don't fail ;) If all goes well, I will rebuild the rest of boost as well and run tests there.

FYI, I've tweaked the boost thread tests to disable language extensions with a modification of the patch I sent earlier. The tests compile and pass both with and without language extensions. Indeed, boost threads builds as it used to as well although the patch does alter this part of boost. If my jam-fu was any good, I'd figure out how to test both combinations automagically if it were necessary. The modification of the patch I sent earlier was basically to have thread/detail/config to say: if msvc && using thread library: // don't need windows api define BOOST_NO_REQUIRE_WIN32 else: // not msvc or building thread library pass Can I get some direction from someone who cares about this? Thank you! Sohail
