    $ set | grep SHELLOPTS
    SHELLOPTS=braceexpand:hashall:histexpand:interactive-comments:monito

Also, CYGWIN environment variable not defined (Sorry I missed this on
previous thread).
    $env | grep CYGWIN

Same behavior under sh and tcsh.  Don't have ash or ksh installed.  Also
same behavior when under command.com:

    $ C:\CYGWIN\HOME\GEOFFREY\TEST>\cygwin\bin\ls FoO
    FoO

Actually dir gets the name right.  (First time I ever saw dir do something
better than ls)

    C:\cygwin\home\Geoffrey\Test>dir FoO
    Volume in drive C has no label
    Volume Serial Number is 3C08-4BE4

    Directory of C:\cygwin\home\Geoffrey\Test

    08/15/2002  06:35 PM                 0 foo
               1 File(s)              0 bytes
               0 Dir(s)   4,451,311,616 bytes free

This is not a show stopper, but is irksome if I have a C and C++ by the same
name like bar.c and bar.C.  Thanks for your help.

What is the behavior on other peoples Cygwin systems?

Geoffrey
