Final decision is left for @rnk and @asl but I'm still against using GCC "internal" headers in the way they aren't supposed to be used. And have MinGW Clang behaving like Linux Clang.

Solving general Clang issue with win32 only fix doesn't seem right.

It will be better to have proper fix than this hackish workaround in limits.h

> There is a problems with limits.h, fix limits.h. Don't make all headers that happens to be in the same directory as limits.h disappear.

There are more issues hidden unless someone tries to compile specific code (ia32intrin.h for an example, I no longer have example however).
