[gnu.utils.bug] gnumake 3.56 "-j" problem

Using multiple jobs doesn't work in 3.56.  I haven't been able to track
it down completely (I gave up after about 2 hours), but it looks like
remake_file() is calling execute_file_commands(), then assigns
file->command_state = cs_finished, even though the job might be running
in parallel and is therefore not finished.  Or maybe it's that 
notice_finished_file() does not set file->update_status.  Or both?
Anyway, here's an example Makefile:
    a: b c
	    @echo a done

    b:
	    @echo doing b

    c:
	    @echo doing c

Here's the output:
    % gnumake -j2
    gnumake: *** Waiting for unfinished jobs....
    doing b
    %

(This occurs on a sun3, sun4, and pc/rt.)
