Yes, but you will also need bits of code from libutil.  If you have all
the necessary bits in a new file, i.e. util.c, then you should be able
to use:

    cc -o date date.c netdate.c vary.c util.c

Extracting the minimal parts of libutil and writing the new util.c file
is an interesting and amusing exercise for a budding C programmer, but
it should be both possible and relatively ``easy''.
