[LLVMdev] Feature request for include llvm-mc in llvm.org/builds

[Reid Kleckner]

I can confirm I get the same behavior, and that's a real bug.  If you use
--target=i686-pc-win32, you get COFF, and that should be a good workaround
for now.  There must be a conditional somewhere that isn't handling mingw
correctly.
