File names on Emacs seldom come as "/foo/bar" without a drive letter.
So we can guess these names are Cygwin names. But even if we don't
want to guess, checking for existent of a directory that is directly
under / is very fast, even on Windows. So we could check that always,
and probably need a user variable to turn that off (for users who,
like me, will never install Cygwin).

If someone writes code to deliver signals to Cygwin processes, I'm
sure we will accept the patches. I know nothing about that except
that it uses some Cygwin-specific magic.
