+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.
