Just run
  ./configure --version

it should tell you.

This bit is macro code from Libtool, it doesn't really tell you about
the Autoconf version you use.

This tests the egrep program, but not really the shell, and neither the
sed program, which is what caused the issues you reported previously.

I don't think this particular text ever came from Autoconf at all.
