Thanks for the tips. I made a completely fresh install in a new 
directory and attempted all three suggestions. Here are the results:

1. That command gets part way through and then hangs with the blinking 
cursor after listing the directories in the path variable.

2. bat file or desktop shortcut hangs with a black window and blinking 
cursor.

3. Set variable and run Cygwin.bat. Black window with blinking cursor.

Literally every single way you can call a cygwin executable just hangs 
with a blinking cursor.
