Can you provide some more details about this? MinGW uses the standard
PE object format, afaik. GCC-4.9 also supports SEH exceptions (on 64
bit, not sure about 32). The mingw 'runtime' is a small layer on top of
the microsoft runtime, to provide C99 functions and similar stuff. I
don't think that should be a problem.

The pdb debug format is not supported, AFAIK. But that format is not
documented and I don't think you could add D extensions anyway.
So does LLVM really support PDB?

MinGW can use dwarf debug info on windows and I guess you get all
benefits of Iain's gdb work on windows. It is annoying if you get
crashes in the microsoft C runtime or any other library compiled with
microsoft tools though, as there's no dwarf debug info for these.

So overall I don't see why mingw should work fine on windows. Of
course there's less incentive for GCC devs to support windows, but I
doubt that's different for LLVM.

There's also nobody working actively on the MinGW gdc port right now,
afaik. We don't even know the test suite results for mingw. So if you
want to contribute...
