As of clang 3.7 there is no need to have a hardcoded mingw directory. 
You just need to have an appropriate mingw(-64)/gcc in your PATH. Also 
all distributed versions of clang 3.4 through 3.7 for Windows default to 
targeting mingw(-64)/gcc and not VC++. Only with 3.8 is the Windows 
release defaulting to targeting VC++.
