dungeon.o depending on lev.h is the only change found by 'make depend'.
(I'm a bit suspicious about that.)
I haven't attempted to reconcile the vms Makefiles with the Unix ones,
just put in this one new dependency. I know vms/Makefile.src lacks
handling for sys/share/*regex.c and vms/Makefile.top and install.com
both lack handling for 'sysconf'.
