  ^^^^^^^^

It took downloading Numeric and NumTut, building and installing Numeric,
and reproducing the error to realize what should have been obvious (to
me) from the above.  Sigh... :,(

The problem is that the standard Cygwin distribution includes a Win32
TCL and not a Cygwin version.  Hence, it is does not understand Cygwin
style (i.e., Posix) paths, mounts, symlinks, etc.

Until a Cygwin TCL is included in the distribution, you can use the
following cygpath workaround:

    $ TMP=$(cygpath -w $TMP) python                                                 Python 2.2.1 (#1, Jun 25 2002, 10:55:46) 
    [GCC 2.95.3-5 (cygwin special)] on cygwin
    Type "help", "copyright", "credits" or "license" for more information.
