CTRL-c fails with bash/NT Emacs

Recently Troy Noble reported and investigated a bug in bash which
caused CTRL-C to fail to interrupt a running subprocess when bash was
executed as a subprocess of emacs.
We have about ten developers using emacs on Windows NT 4.0 SP6 and
Windows 2000 (SP1 and SP2). All developers experience the problem.
Specifically on my own install with:
"GNU Emacs 20.7.1 (i386-*-nt5.0.2195) of Tue Jun 13 2000 on buffy"
(cygcheck is at the end of this message)
To reproduce the problem:
1. start nt emacs with "emacs -q"
2. set the shell environment with
(setenv "SHELL" "d:/usr/cygwin/bin/bash.exe")
Of course, use the path appropriate to your system.
3. Run a subshell with M-x shell
4. Type sleep 100 (or cat)
5. Type C-c C-c
The sleep or cat subprocess will not be interrupted.
I had high hopes that Troy Noble would effect a fix. Thanks for
trying (and for summarizing so clearly your work)!
Cheers,
