[cfe-dev] __builtin_va_list issue with -ccc-host-triple x86_64-pc-win32-macho

Andrew,

It might be dubious in lib/Basic/Targets.cpp.

  case llvm::Triple::x86_64:
    switch (os) {
 (snip)
    case llvm::Triple::Win32:   // This is what Triple.h supports now.
      if (Triple.getEnvironment() == llvm::Triple::MachO)
        return new DarwinX86_64TargetInfo(T);
      else
        return new VisualStudioWindowsX86_64TargetInfo(T);
