[cfe-users] system include not correct

[Jenrry Zhenzhu Tan via cfe-users]

Hi ,

I compiled the llvm and clang from github by Mingw64, and installed it.

When I tried to build a sample cpp source file, the clang++ can't find the standard library includes file,
I googled a lot, but can't resolve my problem.
I will appreciate your help very much.  Thanks
