I think I can fix a longstanding bug in the Cygwin build of emacs, in 
which C-c C-c doesn't work to interrupt a process in shell mode.  Since 
the problem doesn't seem to be in the bug database, I'm reporting it 
first for documentation purposes, and then I'll give the proposed fix. 
To reproduce:

emacs -Q
M-x shell
cat
C-c C-c
(The cat process doesn't get killed.)

The following patch seems to fix it:

I'd like to apply this to the emacs-23 branch.  Does anyone see a 
problem with it or anything further I should test?
