case sensitivity bug?

[Ken Brown <kbrown at cornell dot edu>]

I've set up my Cygwin installation to be case sensitive, following the instructions at

https://cygwin.com/cygwin-ug-net/using-specialnames.html#pathnames-casesensitive

But it doesn't seem to be working as I expect.  For example:

$ mkdir a

$ mkdir A

$ ls -al [aA]
a:
total 100
drwxr-xr-x+ 1 kbrown       None 0 2016-09-20 20:18 ./
drwxrwxrwt+ 1 kbrown-admin None 0 2016-09-20 20:19 ../

A:
total 100
drwxr-xr-x+ 1 kbrown       None 0 2016-09-20 20:19 ./
drwxrwxrwt+ 1 kbrown-admin None 0 2016-09-20 20:19 ../

$ mv a A
mv: cannot move 'a' to a subdirectory of itself, 'A/a'

Why does mv think that A and a are the same directory?

Here's another example, where mv should simply do a rename, but it doesn't:

$ rmdir A

$ mv a A

$ ls -al a
total 100
drwxr-xr-x+ 1 kbrown       None 0 2016-09-20 20:18 ./
drwxrwxrwt+ 1 kbrown-admin None 0 2016-09-20 20:30 ../

$ ls -al A
ls: cannot access 'A': No such file or directory

cygcheck output is attached.
