It's strange indeed. This is with a freshly built m4-1.4 (haven't seen
anything newer).

So does mine.

That fixes it (obviously).

Btw, running ``./configure'' yields

    configure: creating ./config.status
    ./config.status: syntax error at line 1063: `end of file' unexpected

before printing the configuration. That doesn't look normal. The file has
1062 lines and the end looks like

for ac_file in : $CONFIG_COMMANDS; do test "x$ac_file" = x: && continue
  ac_dest=`echo "$ac_file" | sed 's,:.*,,'`
  ac_source=`echo "$ac_file" | sed 's,[^:]*:,,'`

  case $ac_dest in
    default ) \
test -z "$CONFIG_HEADERS" || echo > stamp-h ;;

{ (exit 0); exit 0; }

As a result, some other files aren't being generated (e.g. the Makefile).
