When was the last time you tested that? Clang should be able to produce
executable files, it has support for MS's linker (link.exe) in the driver.

A lot of work has been done on this area lately and it's much better than
it was on 3.2.
64-bit name mangling (http://llvm.org/bugs/show_bug.cgi?id=13792) still
needs some work. There are also some bugs to fix related to lambdas, but
they seem relatively easy to fix.

What kind of improvements do you have in mind? AFAIK 64-bit EH is big gap
in support here right now.
- Frontend compatibility with MSVC C++ headers?

Yeah, intrinsics are the main blocker at the moment to get most of the
broken headers going through. Also, 2012 library needs some relies on some
quirks in preprocessor behavior that needs to be better supported.

I think you've already proven you can work on Clang and MS frontend stuff
with your patches so I'd really love to see you work on improving support
[CC'ing people working on MS/Windows stuff, they might have more ideas]
