pathcch.h lacks include guard

[wjk]

While I was compiling MRTCore-LLVM, I found that for some bizarre reason the copy of pathcch.h included in llvm-mingw lacks an include guard (either #if-based or #pragma once). As a result, my project failed to compile with double-definition errors until I manually edited the file to add such a guard. As far as I can tell, this still happens in the latest version.

The guard is indeed missing in mingw-w64: https://github.com/mingw-w64/mingw-w64/blob/master/mingw-w64-headers%2Finclude%2Fpathcch.h
If you want to contribute, you can send the patch to mingw-w64 mailing list.

This is fixed in mingw-w64/mingw-w64@a0fd211 now, and thus will be part of the next release of llvm-mingw (which probably is due this week).
