[cfe-dev] Trying again - building 64bit code on Windows

[Yaron Keren via cfe-dev]

>Evidently to build a version of clang on Windows targeting mingw-64/gcc,
which can compile 64-bit code, one must build clang with a 64-bit version
of mingw-64/gcc. This may be apparent to you and other clang developers but
it was not apparent to me.

clang may be built with any supported regardless the target. For example,
I'm building clang using Visual C++ 64 bit and targetting the 32-bit
version of mingw. You do need to have the target mingw installed for the
include files, library files and linker.
