Both statements are true, if you allow for transitivity.

configure.ac + autoconf => configure
configure => config.status

Or, in longhand, using autoconf on configure.ac generates a shell script
(configure) which in turn generates another shell script
(config.status).  If you want to change what gets put in config.status,
your options are to alter your configure.ac or to hack on Autoconf.
