I agree that AC_PREREQ should ideally specify the oldest version
possible.
In real-life, I believe the following rough solution might be
sufficient:
- install an oldish version of Autoconf and Automake, test that the
setup works, and write the version numbers to configure.ac
- If a developer complains that a particular combination does not
work, install the versions he reported, and if the problem can be
reproduced, increase the requirements, adding a comment.
At this time, no one should use versions older than Autoconf 2.59 and
Automake 1.9.6. So I suggest that you temporarily downgradde to
these, run "rm -r autom4te.cache&&autoreconf -f" and test the result.
If it seems to work, specify
AC_PREREQ([2.59])
...
AM_INIT_AUTOMAKE([1.9.6])
in configure.ac initially.
(If things work with 2.59 and with the latest devel build, the chance
that they will break with one of the inbetween versions is not that big.)
