I forgot to add, I log into a windows domain and so I can't set the case. 
Perhaps this issue only relates to windows domain logins.  Maybe they are
case insensitive because when I log into the domain, I ALWAYS specify it in
lower case.  I don't think I've ever seen it presented to me (in Windows) as
upper case.  Yet in CYGWIN, $USER=DSMILEY.  If domain logins are case
*in*sensitive (appears likely), then it would seem to me that it should be
normalized to lower-case for use in CYGWIN.
