[cfe-dev] Error building clang from source on Windows with CMake, ninja, and mingw-64/gcc

[Edward Diener via cfe-dev]

Attempting to build clang from the latest source, on Windows 7 with 
mingw-64/gcc-5.3 I get:

Any idea why this is failing ?

If I try with mingw-64/gcc-6.2 I get the same error. Perhaps I need to 
adjust some CMake configuration but I have no idea what I need to change.
