[cfe-dev] State of Clang in MSYS2

Fri Feb 3 04:00:12 PST 2017

I've updated LLVM and Clang patches:
https://github.com/mati865/MINGW-packages/tree/clang-svn/mingw-w64-clang-svn
LLVM patches start with 00xx and Clang patches start with 01xx.

First patch assigned to Reid: https://reviews.llvm.org/D29464
More patches will come soon

Patches are here:
