I was using the current spec, which is here:

http://www.opengroup.org/onlinepubs/009695399/utilities/make.html

The "sh -e" business is clearly incompatible with the POSIX.
POSIX says (1) each makefile command line is passed separately to
system(), and (2) system() does not use -e.  These are old requirements:
they're also present in the older spec that you referred to.

Yes, that's still required -- I didn't know that.  Automake doesn't do
that.  However, it doesn't seem like it would have fixed this problem
so it's probably not worth messing with unless we find a problem that
it actually fixes.
