No.  You can grab similar output from the Autoconf testsuite.
(The line above was just me rerunning `autoconf' inside the Autoconf

I do not know the answer to any of this at the moment, sorry.
(But isn't all that stuff used as well when autoconf is rerun in
third-party sources by Automake's rebuilding rules?)
