Yup.

That won't work. llvm-config depends on the libraries being built. It
extracts the dependencies between the libraries as its main feature. 

Have you read http://llvm.org/GettingStarted.html ?

Its definitely required.

pthread is the posix threading library. I doubt its available on Windows
unless you're using Interix as well (sounds like you're not).  The above
errors are completely understandable for win32.  You can forgo building
the examples by using "make tools-only".

However, the makefiles shouldn't even build this unless pthread is
available. Looks to be a bug in the makefiles.

Good deal :)

You're welcome. Glad you got it built.
