2005-08-07  Paul D. Smith  <psmith@gnu.org>

    Fix a bug reported by Michael Matz <matz@suse.de>: patch included.
    If make is running in parallel without -k and two jobs die in a
    row, but not too close to each other, then make will quit without
    waiting for the rest of the jobs to die.

    * main.c (die): Don't reset err before calling reap_children() the
    second time: we still want it to be in the error condition.
    * job.c (reap_children): Use a static variable, rather than err,
    to control whether or not the error message should be printed.
