66-fyi-general-getopt.patch


From: Akim Demaille
Subject: 66-fyi-general-getopt.patch
Date: Fri, 31 Aug 2001 15:30:45 +0200

Index: ChangeLog
from  Akim Demaille  <address@hidden>

        * lib/Autom4te/General.pm ($version, $help, &getopt): New.
        * bin/autoupdate.in, bin/autoheader.in, bin/autom4te.in: Use them.
        * bin/autom4te.in ($autoconf): Pass --force.
        `print $out' doesn't print `$_' but `$out'.
        * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
        (autoheader): Pass --force since the test suite goes too fast for
        the time stamps.
        Adjust to the new autoheader messages.
