LLVM itself can run when pthreads isn't available, so while some parts
do use pthreads they have alternative implementations for other
systems. Take a look at Mutex.cpp for example: the default is Posix
but there's a Windows specific version in lib/Support/Windows.

There's never (to my knowledge) a situation where both of those are
valid answers: if you're running on Linux you'll use a Linux library,
if you're running on Windows you'll use a Windows library.
Thank you. My question was: is PThreads library for Windows supported by LLVM?

Tim.
