    Yes, I think it could be useful for many programs.

    Or one more option: add a flag to shell that
    will make it exit after any command returning non-0
    status (at the ";" point, as opposed to "&&",
    "||" and such). Then make could just pass all
    the commands to the shell in one go. And it would
    be very useful for all kinds of sysadmin scripts
    as well where explicitly checking for the results
    of every command is a pain. Even with make it
    would be a big improvement, since in the current
    format a command failing inside a "for" loop
    won't cause make to stop unless explicitly programmed
    so, like:

    target: dependencies
       for ... ;\
       do \
         cmd || exit 1; \
       done

    -SB
