Build Errors for ASIO on msvc-10.0 and -11.0

After seeing the announcement that library freeze is coming, I just tried
building the master snapshot with the build scripts I use for building the
windows releases. I encountered failures in msvc-10.0 and msvc-11.0 for
ASIO.

Hopefully this can be cleared up before the beta.
