cygwin emacs: broken key mappings (still?)

["Robert V Sasseen" <rvsasseen at hotmail dot com>]

I'm having a problem with Emacs under Cygwin bash that's been reported 
before but as far as I can tell never been resolved.
See, e.g.,
http://cygwin.com/cgi-bin/htsearch?config=htdig&restrict=&exclude=&method=and&format=builtin-long&sort=score&words=emacs+key+mapping
http://sourceware.org/ml/cygwin/2002-12/msg00086.html
http://sourceware.org/ml/cygwin/2002-12/msg00100.html

The problem is with keys such as c-@ (set-mark-command) not having the 
proper effect. In my case, c-@ has no apparent effect on setting the mark, 
even though m-X describe bindings says it's bound to set-mark-command, and 
even though I can do m-X set-mark-command and it sets the mark properly. The 
keystroke has no apparent affect at all; it's as though it's getting 
intercepted and filtered out along the way.
(I set CYGWIN=tty to resolve the (different) c-C problem discussed in the 
archives, but the c-@ problem is unaffected by this setting.)

Most of the suggested fixes have been of the "don't do that" variety--use 
XEmacs or NTEmacs instead of the Emacs that ships with Cygwin, or use rxvt 
or an xterm in place of Cygwin bash (the latter two ideas both requiring one 
to run X Windows, I believe).

I just installed the latest Cygwin so I'm running GNU bash version 
3.00.16(11) and GNU Emacs 21.2.1. It's running on a new Compaq PC running 
Windows XP Media Center Edition.

Like those earlier posters with this problem, I'm not too sophisticated 
about Emacs, terminals, and the like. But I'd like to truly solve this and 
I'll try anyone's diagnostic suggestions.
