[cfe-dev] [LLVMdev] Clang64 on Windows using Mingw64 yields many linking errors?

I'm wondering if it can be related to the Drangon v4.7.1 release of Mingw64
that I am using?  It is apparently a prerelease, although it works fine for
my program.  In any event, I'd be the last to be surprised if it is simply
me doing something wrong...


Cheers,
