 Last time I tried clang-cl I had to do quite some extra setup IIRC, things 
like having to add -m32/-m64. Since MSVC normally works out of the box, I 
think it'd be better to either have configure check these and add them if 
necessary, or alternatively have some kind of --enable-clang that'd find and 
select clang-cl instead of cl.
