Interesting. We rely on the presence of "favor:" in the output to
determine which platform to use, aka x64 or Win32.

What's the output of cl -help on "z:" in this case? Is the exact same
output as "cl /?" or "cl -help" on c: generated? I have to admit that
I don't really know why things would behave this way, but Windows is a
platform full of undiscovered mysteries, and I have never seen the
output of cl being an issue even for some of my company work, which
uses stuff much more fancy than the normal way of compiling on
Windows, requiring me to patch a bit the scripts of src/tools/msvc/ in
a different way.
