Difficulties with bootstrap script.

[Juan Manuel Guerrero]

I have tried to create a m4 distribution downloading the actual cvs-tree and
using the bootstrap script. I am using:
  gettext 0.14.1
  automake 1.9.5
  autoconf 2.59
  libtool 1.5.14
I have applied the patches to autconf and automake from the README file as
suggested. The first difficulty with the bootstrap script was the missing
of gnulib-tool. I have read all infos contained in the source tree but I have
not found a reference explaining that I had to download the gnulib cvs-tree
manualy. IMHO, the bootstrap script of bison cvs-tree solves this issue in a
quite elegant way automaticaly connecting to subversion.gnu.org and downloading
the needed gnulib cvs-tree into the top level srcdir. After having downloaded
the gnulib cvs-tree manualy and adjusted the path accordingly so gnulib-tool
could be found, I have started the bootstrap process. This process stoped with
the following error message:

gnu/Makefile.am:16: The usual way to define `LIBTOOL' is to add

bootstrap: generating testsuite

As can be seen, AC_PROG_LIBTOOL has not been defined in configure.ac and this
should be fixed. After having fixed this issue the bootstrap process was
successful.
Please note that I do not follow the m4 mailing list on a regular base, so I may
have missed something. May be all this has already been explained somewhere
but I have missed it. Anyway, I hope that the suggestions will be of some help
to you.
