This might be a new gcc 3.3 warning. The ${PROG} target is defined in 
loader's Makefile:

# $FreeBSD: src/sys/boot/i386/loader/Makefile,v 1.66 2003/06/26 03:51:57 
peter Exp $
...
PROG=           loader
...
${PROG}: ${PROG}.bin ${BTXLDR} ${BTXKERN} ${BTXCRT}
         btxld -v -f aout -e ${LOADER_ADDRESS} -o ${.TARGET} -l ${BTXLDR} \
                 -b ${BTXKERN} ${PROG}.bin

Now, bsd.prog.mk also defines a PROG target. It is included later on 
this file:

.include <bsd.prog.mk>

${PROG}.sym: ${OBJS} ${LIBI386} ${LIBSTAND} ${LIBFICL} vers.o
         ${CC} ${LDFLAGS} -o ${.TARGET} ${BTXCRT} ${OBJS} vers.o \
                 ${LIBFICL} ${LIBI386} ${LIBSTAND}


This was added by Mike Smith in version 1.13. It brings in ${OBJS} 
definition and maybe linker stuff (from Mike's commit message).

I'm bringing Ruslan in this. He might be able to help with this.

If you are in the C shell and have just installed a new program, you won't
be able to run it unless you first type "rehash".
