Is there any way for me to get the old behavior? I rely heavily on the
ability to press ctrl-c in my non-cygwin console app and have that app
receive a CTRL_C_EVENT instead of a CTRL_BREAK_EVENT. Everything worked fine
for me before this patch.

It is possible to generate a CTRL_C_EVENT, if you pass 0 as the process
group id, in which case the event is passed to all process that share the
console. Don't know if that would work in this situation.
