I think the Makefile somebody managed to get automake to generate was
calling configure which, when make was again called from inside the
configure script hadn't yet output config.status -- they ended up with
an infinite loop of make calling configure calling make calling
configure calling make....

I've never been able to replicate it with up to date tools, but it fixed
it for them.  So I'm not overly worried if this doesn't go in to 1.5.1,
I was almost toying with not including it in the list but figured I'd
stick everything in as separate patches so we could pick and choose.

The new code for 1.6 doesn't have the problem, as there's no way for
infinite loops like this to occur.

Have you ever, ever felt like this?
Had strange things happen?  Are you going round the twist?
