Thanks - I fixed this, dirty compilation flags.

It's not clear why this happens.  It seems to happen whenever you call
NSApplicationMain () without loading a NIB - eg if you open up
ProjectBuilder with the default Cocoa application project, remove the
MainMenu NIB, then remove the setting of the main NIB from the Info.plist,
you get exactly the same error when NSApplicationMain () is executed; you
also get a default Apple application menu, -- which seems to be loaded
from a framework inside Carbon.framework ?

My guess is that this default NIB which is automatically loaded has got a
buttonPressed: action somewhere.  Opening up the NIB (assuming it is the
one inside Carbon.framework) with Interface Builder does not have a
buttonPressed: action defined, but the menu items are bound to commands
(?) presumably those are later matched to Carbon callbacks via
buttonPressed: ?

Anyway, the warnings seem to be harmless (if not for the fact that it
seems to imply that Cocoa is wasting startup time by loading a default NIB
which is never displayed or used), and maybe we should add -

@implementation NSApplication (shutCocoaUp)
- (void) buttonPressed: (id)sender
{
  /* Do nothing */
}
@end

which shuts Cocoa up, and the buttonPressed: method is never actually
called.
