This was sort of the right track.  It turns out the /usr/bin/sed
shipped with OSX 10.5 does not handle regular expressions like
(this|that) :

        $ echo lex.ll | sed 's,.*/,,; s/\.\(cc\|yy\|ll\)$/.df/';
        lex.ll
        $ echo lex.ll | gsed 's,.*/,,; s/\.\(cc\|yy\|ll\)$/.df/';
        lex.df

This meant that find-defun-files.sh a partially wrong list of files to
mkbuiltins, and builtins.cc contained dozens of complete source files.

I've made a symlink so that "sed" calls the better
/opt/local/bin/gsed, and am trying to build again.

An appropriate patch to submit would be a configure test that checks
whether sed works.  A sexier patch would be to write
find-defun-files.sh.in and allow "./configure SED=gsed".  I don't know
how to do either of these things.
