Thanks.  Nice to see you active in the libtool lists again too :-)

I'm convalescing in San Diego, returning to England in 10 days or so
with new motorcycles.  And then on to the Philippines a few months
later.

Once I've caught up with my gnu mailing list backlog, I'll have about
10 hours a week or so to help out with libtool-2.0 (and then m4-2.0)
for a few months :-)

Bleh :-(

Dusting off my sed-fu, and with wider quoting for Eric ;-)

func_version ()
{[
    $SED -n '
        :a
        /[1-9][0-9]*[,-]$/N; s/[1-9][0-9]*[,-]\n# *//; ta
        /^# '$PROGRAM' (GNU /,/# warranty; / {
            s/^# //
            s/^ *$//
            /\((C)\)[ 0-9,-]*\( [1-9][0-9]*\)/\1\2/
            p
        }' < "$progpath"
    exit $?
]}

That would certainly satisfy the existing func_version sed script, but
I believe RMS dislikes such ranges as they do not make it clear whether
all of the intervening years are covered, or whether they are just the
earliest and latest extremes.  There was some painstaking effort several
years ago to expand such ranges in a project I was watching (perhaps
Emacs, but I don't remember for sure).  If you do want to do that, best
check with RMS first...

Cheers,
        Gary
