The answer is "it's probably not useful".
Make uses implied rules for suffix transformations, so for example there is an
implied target for foo.o which depends on foo.c, which looks something like:
.c.o :
${CC} ${CFLAGS} -c ${.IMPSRC}
These rules represent a few hundred lines worth of build rules which could be
applied to any file as needed in order to build things without having these
rules actually specified in the Makefile itself.

"make -n -d g1 | less"...? Take a look at the main target and at the "parents"
target at the top.
