Well, I probably don't know as much about m4 as you do. But I had a
look nevertheless ....

Well I head a look at the traces. This indicated that lt_combine might
be the culprit. (lt_join uses lt_combine.) Though I didn't know what
this might effect, I made the following change. (More or less just
because _lt_combine looks similar.)

I was pleasently suprised to see, that the loop disapeared. But
instead I got another error:

The error came for every configure.ac where LT_INIT is used without
options. I'd try the following change but haven't got time to test it
now. Maybe someone else can make further investigation.
