I don't want to change the interface to fix something that can be done
otherwise.

You never know whether the macro uses all its arguments or not unless you
know the version of Autoconf and the history of that macro.

This problem will need to be addressed after 2.50. Most likely Autoconf
will integerate "missing". It is quite out of scope of Automake.

AM_PROG_LEX is not affected and should still be used with Automake.

I think I need one more "Ok".
