dnl Autoconf 2.58 defines abs_top_builddir incorrectly, so we
dnl have to require 2.58a, otherwise all our test cases will fail
dnl (abs_top_builddir is used in tests/automake.in).  Note that
dnl this is a requirement for the Automake package itself.
dnl Automake users can still use Autoconf 2.58.

# * Prereleases on the trunk are all incompatible -- 1.5b and 1.5c
