config.status is run, after creating it, by the 'Makefile' rule:

  configure: creating ./config.status
  configure: WARNING: This configuration installs a 'movemail' program
  that retrieves POP3 email via only insecure channels.
  To omit insecure POP3, you can use './configure --without-pop'.
  MAKE='make' ./config.status
  config.status: creating src/verbose.mk
  config.status: creating nt/emacs.rc
  config.status: creating nt/emacsclient.rc
