AC_INIT_NOTICE claims:
# Generated automatically using Autoconf version ]AC_ACVERSION[
# Copyright (C) 1992, 93, 94, 95, 96, 98, 99, 2000
# Free Software Foundation, Inc.
#
# This configure script is free software; the Free Software Foundation
# gives unlimited permission to copy, distribute and modify it.
The configure script consists of pieces copyrighted by the FSF and
other pieces copyrighted by the author of configure.in, who may or may
not be the FSF. Autoconf has no way of knowing what the licensing
conditions of configure.in are, or who the authors are. All it can
say is that the portions of the configure script that are part of the
autoconf package have unlimited permission to copy, distribute and
modify.
As it currently stands, a configure.in script which is merely GPLed
would be legally _required_ to redefine AC_INIT_NOTICE.
(Forgive me for being pedantic, but I've learned from rms)
Which makes it tougher to portably incorporate the variable
definitions in AC_INIT_NOTICE:
ac_arg_with_help=
ac_arg_enable_help=
...
More generally, the initial copyright notice should be separated
logically from the initial variable initialization. Try to think
about some other mechanism to include default variable values.
Probably you have some reason for why ac_arg_with_help and friends
cannot be initialized in AC_INIT_PARSE_ARGS, for example, where other
variables are initialized.
One way to allow separate overrides is:
AC_DEFUN(AC_PACKAGE_COPYRIGHT_NOTICE,[]) dnl override me
AC_DEFUN(AC_FSF_COPYRIGHT_NOTICE,
[# Generated automatically using Autoconf version ]AC_ACVERSION[
# Copyright (C) 1992, 93, 94, 95, 96, 98, 99, 2000
# Free Software Foundation, Inc.
#
dnl must be a better way to say that...
# The portions of this configure script generated by autoconf are
# free software; the Free Software Foundation gives unlimited
# permission to copy, distribute and modify them.
]
AC_DEFUN(AC_INIT_NOTICE,
[AC_FSF_COPYRIGHT_NOTICE
AC_PACKAGE_COPYRIGHT_NOTICE
AC_INIT_DEFAULT_VARIABLE_VALUES
]
although I would still look for a better place to initialize
variables than AC_INIT_NOTICE
