[cfe-dev] Clang and Visual Studio/Microsoft STL compatibility

[Steve Frankwilde]

Hello,

I have a couple of quick questions about Clang's current level of C++ 
compatibility with Visual Studio.

-When targeting VS, is Clang able to be used to generate MS ABI 
compatible code for any version of Visual Studio and in particular VS10 
or 11? Can you pass complex (non POD) data types between VS and Clang 
compiled code without resorting to COM methods like abstract interfaces?

-From what I've read Clang is currently unable to compile the VS10/11 
STL due to Microsoft extensions, (roughly) how much work would be 
involved in getting Clang to fully build the MS STL?

Thanks very much.
