Problems like this are why I would strongly recommend that anyone
tracking -current use obj/ dirs.  Then, if you run into a problem you
can look for files in obj/ that were not cleaned up by 'make
cleandir'.

In the case of csh, err.h was left behind because it was renamed to
errnum.h in the Makefile; once that happened, 'make clean' only knew
to remove errnum.h, and any leftover err.h files were left behind.
Then when csh was built, gcc #included <err.h> from
src/bin/csh/{obj/,} instead of /usr/include, and warnings were the
result.
