>Description:
libobjc redefines the MIN and MAX macros previously defined in
sys/param.h. During a buildworld warnings are issued:
/usr/src/gnu/lib/libobjc/../../../contrib/libobjc/encoding.c:35: \
warning: `MAX' redefined
/usr/obj/usr/src/i386/usr/include/sys/param.h:214: \
warning: this is the location of the previous definition
/usr/src/gnu/lib/libobjc/../../../contrib/libobjc/encoding.c:39: \
warning: `MIN' redefined
/usr/obj/usr/src/i386/usr/include/sys/param.h:213: \
warning: this is the location of the previous definition
>How-To-Repeat:
compile libobjc
