commit b4113eba0c42054a7caf6377a57b28cfd775381d
Author: Ralf Wildenhues <address@hidden>
Date:   Sun Sep 13 10:05:10 2009 +0200

    Improve autotest testsuite summary message.
    
    * lib/autotest/general.m4 (AT_INIT): Hint at the toplevel log
    only if not $at_debug_p.  Always hint at the per-test output.

Date:   Sun Sep 13 10:03:51 2009 +0200

    Four new autoupdate tests, expected failures.
    
    * tests/tools.at (autoupdating macros recursively)
    (autoupdating with m4@&address@hidden, autoupdating with AC_REQUIRE)
    (autoupdating with complex quoting): New tests.

    Fix description of AC_CHECK_LIB regarding other deplibs.
    
    * doc/autoconf.texi (Libraries): Library linking may not fail
    even without missing additional libs.
