    Fix the warning message about AC_OUTPUT:

     Replaced AC_OUTPUT(list...) with an AC_OUTPUT without arguments, and
     AC_CONFIG_FILES listing the files.
    
    Fix the warning message about AC_OUTPUT:
    configure.ac:428: warning: AC_OUTPUT should be used without arguments.
    configure.ac:428: You should run autoupdate.
