There was one hack how to push ${DJDIR} through recursive makefiles I took
from sources of GNU Pascal and used in port of gcc-2.95.2 to DJGPP.

Anyway runtime conversion of /dev/env/DJDIR to $DJDIR (so gcc and other
programms sees value of $DJDIR instead) is of course better than trying
to force ${DJDIR} not to be evaluated.
