Modified the main OS X interface module to remove the use of setjmp() and longjmp(). The MainMenu.nib file was modified to invoke the stop selector instead of the terminate selector on the NSApp object. This allows the OS X framework to return from the call [NSApp run] instead of using setjmp()/longjmp() in a managed framework.
