So you can use one or the other depending on whether you think that the comment is for the person reading "configure" or just "configure.ac". # is actually the m4 comment character. From the m4 manual: 3.3 Comments in `m4' input ========================== Comments in `m4' are normally delimited by the characters `#' and newline. All characters between the comment delimiters are ignored, but the entire comment (including the delimiters) is passed through to the output--comments are _not_ discarded by `m4'. -- "While the Melissa license is a bit unclear, Melissa aggressively encourages free distribution of its source code." --Kevin Dalley <kevin@xxxxxxxx> _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
