So you can expect it to "work" only outside of any mount point?

It doesn't seem to do this for me (using 20050101 snapshot):

$ CYGWIN="$CYGWIN check_case:adjust " bash
$ echo $CYGWIN
tty ntsec title server check_case:adjust
$ cd c:/SeTuP/CyGwIn
$ /bin/pwd
$ ls -d c:/?e?u?/?y?w?n

I'm afraid I'm not curious enough about this to try older versions
at the moment.  cygcheck output attached in case you are interested.
