When I first ran it (on a mac) it complained like this, over and over
again:

  sed: -e expression #1, char 40: unterminated address regex
  sed: -e expression #1, char 36: unterminated `s' command

These were in the expressions that extract the MACRO: and TITLE: stuff
(see patch).  Turns out the "sed" getting run was the sed in the
"fink" installations, not /usr/bin/sed.  Following patch fixes it
(just change "sed" to "/usr/bin/sed", which is a reliable location for
sed on all the unices I know of).  Probably you would want to do this
for all uses of seds, perhaps first check for /usr/bin/sed and then
fallback to whatever sed is in the users' path, if any.  Haven't
looked at gnu autoconf to see how they do this kind of thing...

I figured out what GNU sed's first complaint was, it doesn't like
this:

macroname=`cat $file | grep '^//[]    []*MACRO:' | sed 's/.*MACRO:[]    []*\([]_A-Z0-9[]*\).*/\1/'`

but it does like this:

macroname=`cat $file | grep '^//[]    []*MACRO:' | sed 's/.*MACRO:[]    []*\([_A-Z0-9]*\).*/\1/'`

And I didn't get to figger the TITLE: problem.  Dunno.
