As Nobu said, though, this may be a problem with VisualC++ compiles; I
don't have VC++ on this machine to test. I might be able to test it this
afternoon when I pick up my laptop from the office, but since \ is a
directory separator in Windows, it isn't going to be a quote escaper on
the shell.

Ruby may need to do a bit of extra work here. :(
