B19.1: problem with alien gdb and signals

[Curtis Galloway]

I'm using the version of GDB that comes with Apple's OpenStep distribution. 
Under b18, it worked well.  Under b19, when I use Ctrl-C to interrupt the
program being debugged, gdb quits immediately as well.

Anyone have any clues as to why this could be happening?  I did make one
change in winsup/execeptions.cc, but I don't think it would affect this. 
(I've included the diff below -- it solves the problem of having the "End
task" dialog panel appear for each cygwin process window that's open when you
shut down the computer.)
