[LLVMdev] Undefined references when LLVM is configured with "--host=x86_64-gnu-linux --target=x86_64-w64-mingw32"

[Ruben Van Boxem]

Hi,

I'm getting a returning build failure when building a linux->windows
crosscompiler out of LLVM/Clang.

Attached is config.log and below is the output of "make VERBOSE=1"

This is not a new failure (I had it about a month ago too, but ignored
it and never tried again, untill now). Any assistance is appreciated.

Thanks,
