how to get make to terminate itself at the first error?

[Martin d'Anjou]

Hello,

In jobs.c, when I introduce a call to fatal_error_signal(SIGTERM) here:

if (err && block)
  {
    static int printed = 0;
    fflush (stdout);
    if (!printed)
    {
      error (NILF, _("*** Waiting for unfinished jobs...."));
      fatal_error_signal(SIGTERM);
    }
    printed = 1;
  }

parallel make terminates at the first error. However, jobs don't appear to 
die equaly, as some jobs keep running, and when I use process substitution 
t=$(make -j 2), it won't return unless the jobs are gone from the process 
table.

Here is the makefile that I used:

all: t2 t3
t2:
        sleep 10 && exit 1
t3:
        sleep 60 && echo done t3 || echo failed t3

What is the correct way to have make self-terminate one the first error
as if control-C was hit on the command line?

Thanks,
Martin
