I have some experience in this area.  A few years ago I used this
library:

  http://sourceware.org/pthreads-win32/

to do pthreads sorts-of-things within the win32 API (this was native
code, not using the not-very-useful win32 POSIX layer).  I too was
using Visual C (C++ actually...).

A couple of potential gotchas that I ran into at the time:

1:  pthread_kill() wasn't able to signal other threads, even in the
same process.  The win32 thread model doesn't support this.

2:  it wasn't entirely clear to me when I audited the code where all
of the pthread_cancel()-able codepoints were.  Caveat programmer...

3:  I had some difficulty with pthread_cancel()-related cleanup
functions. 

3:  In C++ code, exception handling was a bit flaky.  Sometimes some
of my destructors weren't called.


Other than these problems (which I was able to code around), I found
this library to be of very high quality.
