Re: NSOutlineView compilation error

[Gregory Casamento]

The ## is needed to paste the name of the method being checked for.   Simply
replacing it as you have done *will not work* as now it is looking for a method
named "selector_name".  The "errors" you mention are preprocessor warnings and
are harmless.

This warning does not appear when using gcc < 3.0.
