No, that's not my goal.
I'm not concerned about _my_ Makefile.am, now when I know. I was thinking
about people who don't know all the details of make, yet they suppose that
it'll do the right thing. They could benefit if we switch on the correct
behaviour by default.
I knew that make removes the target if it is interrupted. I kind of
supposed that it does the same if a command failed.
When I looked at the manual of GNU make, I read: ``yeah, we know that
would be the right behaviour, but we cannot enable it by default
because of bug compatibility.'' I understand that.
But I think this doesn't apply to Automake; Automake should try to
enable the correct behaviour by default.

Actually, the only error I observed was that I screwed the path and the
generator wasn't found.

I was thinking about creating foo.h.tmp and renaming it.
This is more elegant solution, thanks.
Thanks,
