The file utils cat program built with djgpp does this too.  So both
cat \\cws333\d$\djgpp\setup.bat and cat z:\\cws333\d$\djgpp\setup.bat
work.

Even more interesting, cat \:\\cws333\d$\djgpp\setup.bat works.
On both Windows 2000 and Windows 95.  Some real potential for abuse
here :-)

This might allow psuedo disks to go to calls that want them but allow
the required stuff to still work.
