[cfe-dev] Mingw-builds mingw-w64 include directories

[Nikola Smiljanic]

Hi Johan, I think that we're trying to move away from logic in
InitHeaderSearch. The idea is to implement MinGW toolchain and the same way
we have Windows, GCC and other toolchains. Last thing I heard Ruben was
working on this (+CC)

Search for thread titled "Clang and (cross-)compilation to [i686,
x86_64]-w64-mingw32" on the mailing list for more info.
