    Yes, possibly followed by "sleep 10", or some other annoyingly long 
    delay.

Idea!  We could put in an infinite sleep-loop.  Then the make will not
get beyond that point.  You'll have to use C-c to terminate it,
though.  Does that seem unreasonable?

Seems entirely reasonable to me.

`make -j' will still get beyond that point, of course.
I feel like we're trying too hard to solve a non-problem.
Let's just put a `sleep 10' and be done with it.

To make C-c more reasonable, we could add an appropriate text before
the sleep, telling the user to stop it with C-c.

What about making the ${SUBDIRS} and leim targets depend on
maybe_bootstrap?  Then "make src" will get the warning too (is that a
bad thing?), and "make -k" should skip all the subdir targets after
the one failure reported by maybe_bootstrap.

That sounds good.

    Assuming that make expands $$ to it's PID, does it ?

I think make starts a shell to run the command, so $$ will
be the PID of the shell.  So I expect it would not work.
Have you ever seen it ever work?

Actually, `$$' is turned into `$' by make (since $ is used by make for
variable interpolation, `$$' is provided as a way to protect a $ from
expansion).  So `$$$$' would get the shell's process id.

With some shells you might be able to use `$$PPID'.

I stand corrected, but this doesn't affect the point.  The shell's
process id is not useful anyway--killing the shell is easy with `exit
1', but that won't tell `make -k' to stop.
