Rats.

Ah, that piece of code looks very different from the one of autoconf
2.61 :)

So, just to check I understand right, when you say the error messages are
"the same with different line numbers", it means the following?

 ./configure: line 6251: could not make ./config.status
 ./configure: line 6255: test: too many arguments

Then, I'd like to look at the values of "$ac_delim_n" and
"$ac_delim_num"; insert

  printf "%s: '%s'\\n" '***** ac_delim_n' "${ac_delim_n}"
  printf "%s: '%s'\\n" '***** ac_delim_num' "${ac_delim_num}"

just before the line:

 if test $ac_delim_n = $ac_delim_num; then

My guess is that $ac_delim_n or ac_delim_num contain spaces, but given
how they are defined, I don't see how this can happen, unless your
grep does funny things. Can you try in a shell:

printf 'a\nb\na\nb\na\nb\na\nb\na\nb\n' | grep -c a

It should output just "5" (and a newline) and nothing else.

If I'm right, then an immediate fix for the "test: too many arguments"
error is to replace the line

  if test $ac_delim_n = $ac_delim_num; then

by

  if test "$ac_delim_n" = "$ac_delim_num"; then

But I would like to understand how they come to have a weird value.
