Objective-C shows the advantages of the GPL. Since the writers of the compiler, NeXT, wanted to use GCC's backend, they had to make their frontend GPL'd too. As a result, there exists a public Objective-C compiler, and that has done neither NeXT nor Apple any disfavours. -- Alan Mackenzie (Nuremberg, Germany). _______________________________________________ gnu-misc-discuss mailing list [email protected] http://lists.gnu.org/mailman/listinfo/gnu-misc-discuss
