<para>This takes a long time, about &autoconf-fin-sbu-tests; SBUs. In addition,
several tests are skipped that use Automake. For full test coverage,
Autoconf can be re-tested after Automake has been installed. In addition,
two tests fail due to changes in libtool-2.4.3 and later.</para>

<note><para>The test time for autoconf can be reduced significantly on a
system with multiple cores. To do this, append
<command>TESTSUITEFLAGS=-j<N></command> to the line above. For
instance, using -j4 can reduce the test time by over 60
percent.</para></note>
