break (C-c C-C) in shell broken

[fred]

I am using all the time a shell window from emacs and it 
used to be the case that Control-C Control-C would send a 
break to the shell. It is a feature I use all the time
(specially when doing SQL queries).
However, it stopped working just recently. 
Local unix system engineers couldn't help. 

I use: 
GNU Emacs 21.2.1 (sparc-sun-solaris2.8, Motif Version 2.1.0) of 2002-09-10 
GNU bash, version 2.03.0(1)-release (sparc-sun-solaris)

I also tried to recompile and reinstall emacs today with no success. 

Any help would be greatly appreciated. thanks.

fred.
