[cfe-dev] stddef doesn't support for wint_t at windows mingw.

[罗勇刚(Yonggang Luo)]

> output of something like "clang -v hello.c"?

Because of I copied those files that placed at Headers into
D:/Tools/Building/llvm/lib/clang/1.0/include,
And also I copied those headers of mingw-rt and also mingw-w32 into
D:/Tools/Building/llvm/lib/clang/1.0/include
And I used three file comes from Headers overwrite those files comes
from mingw.(float.h stdint.h limits.h)

So it's working.

And also, because I doesn't installing mingw at c:/mingw,
So c:/mingw/include doesn't exist. Maybe it's the problem.
And also I doesn't installing gcc at c:/mingw/include.
And I am working at msys.
By the way. I am confusing why clang calling gcc.exe as a driver and
so it's required mingw-gcc package.
even though I doesn't install it. And just placed it at the
environment variable.
So gcc is working.
And if I placed binutils at clang/1.0/bin. It's not working.
