Although I got absolutely zero response to this request, I did find an
answer.  With the error checking turned off, what I ended up doing was
approximately this:

	chdir(new_dir);
	getcwd(new_dir, MAX_PATH_LEN);

It works beatifully, on both VMS and unix.  (And probably DOS, but
I wouldn't bet my life on it.)
