Thanks for the detailed bug report, and for the patch.
I installed the following patch instead; it's a bit more conservative.

* bin/autom4te.in (handle_traces): [^ *\(.*\) *$] ->
[^ *\(.*[^ ]\)? *]. The old regular expression was obviously wrong,
and it blunders into a GNU m4 bug as noted by Martin Frydl in
<http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>.
