It should be simple for everyone to determine where the macro came from originally, who wrote it, and where the latest version can be retrieved. To achieve this, every macro used to start with a distinguished line that shows the URL of its respective home page, i.e.: | ##### http://autoconf-archive.cryp.to/ax_prog_acme.html As it happens, the aclocal utility distributed with Automake ignores all comment lines that start with a double hash '##', thus those home page URLs will not make it into any automatically generated aclocal.m4 file. Duh. To remedy the situation, the following markup is now used instead: | # ================================================================= | # http://autoconf-archive.cryp.to/ax_prog_acme.html | # ================================================================= * The 2.x versions of the GNU GPL and LGPL contain the following clause: | You should have received a copy of the along | with this program; if not, write to the Free Software Foundation, | Inc., 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA. Version 3.x, however, smartly refers the reader to the Web: | You should have received a copy of the GNU General Public License | along with this program. If not, see . This patch changes all GPL2 and LGPL2 macros to do the same, i.e. to refer to the GNU web site for the full text of the respective license. * Since all m4 files had to be changed in this commit anyway, the opportunity was used to increase the auto-fill column for documentation from 65 to 75 characters per line. It's a trivial change, but it just looks nicer. --- m4/ac_check_func_in.m4 | 50 ++++++++++++++++++++++++-------------------------- 1 file changed, 24 insertions(+), 26 deletions(-) (limited to 'm4/ac_check_func_in.m4') diff --git a/m4/ac_check_func_in.m4 b/m4/ac_check_func_in.m4 index e88e4e6..c0328d3 100644 --- a/m4/ac_check_func_in.m4 +++ b/m4/ac_check_func_in.m4 @@ -1,4 +1,6 @@ -##### http://autoconf-archive.cryp.to/ac_check_func_in.html +# =========================================================================== +# http://autoconf-archive.cryp.to/ac_check_func_in.html +# =========================================================================== # # SYNOPSIS # @@ -10,41 +12,37 @@ # # LAST MODIFICATION # -# 2006-10-13 +# 2008-04-12 # # COPYLEFT # -# Copyright (c) 2006 Guido U.
