Just to avoid the spread of misinformation, tcsh also doesn't use
case insensitive hashing.  It used to convert the hash table to
all lower case, see
http://sourceware.org/ml/cygwin-announce/2005-06/msg00007.html

This has been reverted in 6.14.00-4 so that the case is now taken as is
again.  See the discussion taking place in
http://cygwin.com/ml/cygwin/2005-06/msg00559.html

Cygwin tcsh does not share its hashing code with the Win32 version, it
uses the same code as all other OSes are using.  No other OS is using
case insensitive hashing, so doesn't Cygwin tcsh.
