This does no harm on GNUstep.  However, please indent with two spaces,
and place spaces after -, :, and ):

- (BOOL) validateToolbarItem: (NSToolBarItem *) toolbarItem
{
 return [toolbarItem isEnabled];
}

Otherwise, LGTM.  Thanks.

OK, I've attached a new version of the patch.  Konrad, could you check
if with this patch the Emacs toolbar works as you expect?  Thanks.

Thanks, installed on the emacs-29 branch, and closing the bug.
