[cfe-dev] Clang unit test failure / Windows

[Yaron Keren]

I have seen the export problem. As you say it resolved itself after
restarting the make.
You need mingw gcc 4.8 at least. mingw-w64 and all tools versions sounds OK.
compiler-rt not required.

Are you using MSYS2 for the shell functionality?
