System: NetBSD vivax.bernstein.com 1.2G NetBSD 1.2G (VIVAX) #2: Thu Sep 4 07:55:32 EDT 1997 root@vivax.bernstein.com:/import/tardis/usr/src/sys/arch/vax/compile/VIVAX vax


>Description:
	
If vers.o does not exist, the VAX boot programs will not build.
This problem is masked by a related problem:  "make clean" does not
remove the vers.o object file.
>How-To-Repeat:
	
# cd /sys/arch/vax/boot
# rm -f *.o
# make clean && make cleandir && make depend && make
[... churns for a while ...]
make: don't know how to make vers.o. Stop
# touch vers.o
# make
[... build completes successfully ...]
