Look at the -L option in the man page for 'ld'.  It allows you to set
the directories 'ld' will use to search for libraries you have named
with -L.  For example, you can name your library libmylib.a, put it in
/usr/people/me/lib, and then have a link line that looks like

	cc ..... -L/usr/people/me/lib ... -lmylib

(cc just calls ld to link.)  This isn't much help for just one private
library, but its great if you have several.

The -Zg option is obsolete on 4D systems and should not be used.  It is
equivalent to using '-lgl -lm' in the link command.  Besides, explicitly
saying -lgl makes it easier to change to -lgl_s and back.
