Not so surprising, as they never claimed to have a better language
support, just a better STL support.

I doubt there will be much use in trying to support the MSVC
compiler. What I think would be a viable way, is to support Visual
Studio in the infrastructure and use some other compiler, either ICC
or clang++.

Andreas (Nüßing) made some good progress compiling dune under
Windows. If we follow my sketched route, the "only" thing is that the
libc on Windows is not POSIX complient. But most parts of DUNE don't
make libc calls directly.

Anyway... thanks for trying this out and keeping us up-to-date.
