[LLVMdev] Cross-compiling llvm/clang osx -> win32

[NAKAMURA Takumi]

Antonie,

I wonder you would need pecoff-aware binutils.
That said, I have not tried building compiler-rt as cross-build
targetting to Win32.

You might attempt;

  - Obtain mingw32-cross binutils, i686-pc-mingw32-XXX.
  - Build the tree with --target=i686-pc-mingw32.

I will attempt such a configuration later.
