Just having "mount.exe" and "cygwin1.dll" in the same directory and running
"mount" should be adequate.

If "mount" exits with a "multiple cygwin problem" then, well...

If "mount" shows more than just /cygdrive paths, then cygwin isn't installed
in any useful way.

This uses standard tools to check and avoids the assumption that checking
the registry is always going to be the best way to find out if cygwin
is installed.
