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