When building LLVM/Clang, I get the following build failure:

mingw32-make[2]: ***
[lib/Support/CMakeFiles/LLVMSupport.dir/Signals.cpp.obj] Error 1

MinGW-w64 provides the necessary typedefs and declarations. I adjusted the
ifdef's to include a check for a the MinGW-w64-specific symbol of choice to
differentiate mingw.org vs mingw-w64. Tested on i686-w64-mingw32 and
x86_64-w64-mingw32.

Please comment or apply. (I am not subscribed to llvm-dev, sorry :-/)
