>Description:
"make -j2" in /usr/src/bin/csh fails due to missing dependencies
on generated header files const.h and error.h.
>How-To-Repeat:
$ cd /usr/src/bin/csh
$ make -j2

*** [const.o] Error code 1

make: stopped in /usr/src/bin/csh
(There may be slight differences as I'm reporting this from a
Debian system.)
This doesn't happen in non-parallel mode as alloc.o does depend
on const.h and error.h, and normally gets built first.
It also doesn't happen if "make depend" is run beforehand, but
I think explicit dependencies would still be a good idea.
>Fix:
With the exception of char.c, all csh sources include csh.h,
which in turn includes const.h and error.h, so a simple fix is
to make all ${OBJS} depend on them as well:
