I then tried compiling a dead simple hello world program and ran into some linker errors I can't quite figure out.  I reduced the necessary code to cause some of the errors down to this:

Clang's implementation of MSVC's C++ ABI is still very minimal, and it's unlikely that you'll be able to get Clang to produce code which would interoperate correctly with Microsoft's standard library, even if it linked successfully.  We'd *love* to see more work on this, though.

That said, it looks like Clang is producing code for the Itanium ABI;  it's probably compiling as if it were targeting mingw.
