Subject: * lib/Autom4te/General.pm ($version, $help, &getopt): New.
X-Git-Tag: AUTOCONF-2.52d~15
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b7e99feee5b060bc0dd895525a18b1f0c71fc8a0;p=thirdparty%2Fautoconf.git

* 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.
