I was not looking hard enough.

While my other mail about the necessary export autoconf header is
correct (but not fixed yet), the libtool patch mentioned above also
has m4 syntax errors in it.  These will prevent Libtool HEAD from
bootstrapping also with older Automake. 

The patch below fixes that.  If I can't get a solution for Automake
HEAD quickly, I'll install this part separately.

Cheers,
Ralf
