Make deps=msvc experimentally available on non-Windows.

This makes it possible to run most of the clparser tests on non-Windows,
and is potentially useful for cross-compiling on non-Windows hosts.
Also, the manual didn't document this as Windows-only previously.

If you use this on non-Windows, please let me know, else I might undo
this change again in the future.
