Here are my first results, before and after applying the fix, on Jim's
files.

/tmp/fileutils-4.0.37 % time ace                                 nostromo 15:07
configure.in:81 9999            
configure.in:19 10000
configure.in:17 40
configure.in:2 -1
NONE:0: the top level
$ace/autoconf -A $ace  14,84s user 0,68s system 99% cpu 15,612 total
/tmp/fileutils-4.0.37 % time ace                                 nostromo 15:14

configure.in:2 -1
NONE:0: the top level
$ace/autoconf -A $ace  14,73s user 0,77s system 99% cpu 15,576 total

Here is the time without the diversion tracking:

/tmp/fileutils-4.0.37 % time ../autoconf-2.49c/autoconf -A ../autoconf-2.49c
../autoconf-2.49c/autoconf -A ../autoconf-2.49c  14,26s user 0,89s system 93% 
cpu 16,243 total


I'd say it cost less, so let's go for this check! (I want this check
because in the case of JIM, AC_OUTPUT was almost in the middle of
configure!!!  Diversions where completely broken as demonstrated
above: there are still two additional tmp diversions opened).
