Fair enough.

I've tested now (sorry for not doing that earlier).  It's something
else.  For now I can only presume it's bug in the Libtool m4 macros
(manifests itself with branch-2-0 and HEAD of Libtool).  Thanks for
making me look again!

I have no idea yet how to localize this guy, so here goes a copy for the
libtool-patches list:  This patch[1] causes bootstrapping of Libtool
branch-2-0/HEAD to fail.  I presume a bug in our macros.  The failure is
(./bootstrap output):

| autoreconf: Entering directory `.'
| autoreconf: configure.ac: not using Gettext
| autoreconf: running: aclocal --force -I m4
| configure.ac:186: /usr/local/bin/m4: ERROR: Recursion limit of 1024 exceeded, 
use -L<N> to change it
| autom4te: /usr/local/bin/m4 failed with exit status: 1

Ralf
