[gcc]
2002-08-26 Ziemowit Laski <zlaski@apple.com>
* objc/objc-act.c (get_super_receiver): If inside a class method
of a category, cast the receiver to 'id' before accessing the 'isa'
field so that <objc/objc-class.h> is not needed. For NeXT runtime.
[gcc/testsuite]

* objc.dg/super-class-2.m: New test.
