Actually Boost.Thread gives you the option of whether it drags in 
windows.h or not via a macro. By default it does not and therefore 
must speak MSVC intrinsic.

The failure on mingw is because mingw appears to have suddenly 
stopped implictly defining the MSVC intrinsics. As I mentioned, 
mingw-w64 or older mingw's are fine. Boost.Thread in trunk is now 
fixed and no longer attempts to use intrinsics on mingw.

Mingw, quite frankly, is very brittle and has lousy QA. Proposed 
Boost.AFIO currently hangs on the latest Mingw due to yet another new 
bug, this time they've broken directory enumeration somehow. I'm not 
going to bother working around it, I'm simply telling people go use 
Mingw-w64 which is far less buggy. Or use MSVC like sane people do on 
Windows.
