Windows is not going to understand Cygwin's POSIX paths.  So you either
have to translate them using 'cygpath' or set things up so there's enough
coincidental correspondence between the two "systems" to make it work.
This means either installing Cygwin in the root directory of the drive
that you'll commonly be working in with both Windows and Cygwin tools
or creating parallel links to Cygwin directories for largely the same
effect.  To accomplish the former, you either install (or reinstall) Cygwin
to the root of the drive you want or you move it (as you asked) and fix
up the mount points (and cygwin.bat, startxwin.*) paths to use the new
location.  To accomplish the latter, use something like 'junction' to
create directory symbolic links, windows will understand, and that point
to the appropriate directories in your Cygwin installation, no matter where
it is.  This assumes you're working with NTFS of course.  Junction is
available here:
