Terminate NSApp gracefully when receiving SIGNIT. )Fwd: [Etoile-discuss] Etoile 0.2 on Solaris)

[Yen-Ju Chen]

Hi,

  Here is a patch from David to terminate NSApp gracefully
  when an application receive a SIGINT signal.
  It is what NSApp on Cocoa behaves.
  So it is nice to have it in GNUstep.

  Thanx.

Or I could just implement it.  Here's the diff, let me know if you
have any problems (if there aren't any, can someone push it upstream;
the FSF now have my copyright assignment form):
