With new Autoconf, you can use
  ./config.status --config

to get at the arguments in a reusable way; see `info Autoconf
"config.status Invocation"' for how to use this.  Older releases provide
only
  ./config.status --version

but it needs some work to reuse.  Within configure, $ac_configure_args
serves the same purpose (and needs an 'eval' too) but is not defined.

Cheers,
Ralf
