>Description:
The patches enable you to compile Objective C code as you would
C++ or C code without jumping through hoops in /etc/make.conf or
Makefile.
-Wno-import is not my call to make. I put it in there because
I felt that most Objective C users would come from a NeXT background
and would use #import. For all I care, those people can tack it
onto CFLAGS.
