* tests/stamph2.test: Strengthen.
* tests/confh2.test, tests/confh3.test: Remove.
These are bad tests: they don't check the effects, but some

invocation syntax for config files and headers.

filenames in order to support 'nobase_'.

* automake.in (handle_languages, handle_single_transform_list,
lang_c_rewrite): Use require_conf_file instead of
require_config_file to require depcomp or compile from
Makefile.am.  (This is a part of my patch of 2001-10-15 which got
mistakenly reverted.)

* tests/confh.test: Since 2001-10-20 Kevin Ryde, stamp-h is

name (AC_OUTPUT or AC_CONFIG_FILES) for error messages.

* automake.in (&require_file_internal): Instead of $file and $line,
take $where as first argument.
Adjust all callers.

Use it where internal black magic was used to recover the location
of a macro definition.

* automake.in (&read_am_file): Define and use `$here'.
Avoid using am_line_error.

* automake.in (&am_target_error): New.
Use it where appropriate instead of...

Using it for a target is a croak error.

since AM_INIT_AUTOMAKE requires them.

* tests/defs (configure.in): Use credible AM_INIT_AUTOMAKE
arguments.
Don't run AC_ARG_PROGRAM another time, it is required by
AM_INIT_AUTOMAKE.
* tests/aclocal.test: Work on the default configure.in
* tests/config.test (configure.in): Don't AC_ARG_PROGRAM.
First AM_INIT_AUTOMAKE, then AM_CONFIG_HEADER.
Be realistic in testing: AC_INIT is required for Autoconf.
Broken so called optimized tests break trace handling.

* tests/version2.test: Add AC_INIT in `configure.in'.

* automake.in (&scan_autoconf_traces): Add support for
AM_INIT_AUTOMAKE, AM_CONDITIONAL.
Let @args have a more natural M4 correspondence: $1 is args[1], no
args[0] etc.
(&scan_autoconf_files): Using autoconf traces is no longer a
complement of the previous ad hoc scheme: use either.

* automake.in (&scan_one_autoconf_file): `%generalize' is new, and
factors dedicated $libsources assignments.

* m4/error.m4, m4/obstack.m4, m4/ptrdiff.m4, m4/strtod.m4:
Remove, since Autoconf 2.52 has them.
* automake.in, aclocal.in, automake.texi: Adjust.

* automake.in (&read_main_am_file): s/generated automatically/
generated/.
Insert @configure_input@, since 2.50 no longer output this
automatically for Makefiles.

* lib/am/check.am (check-TESTS): Add an "else true" to work with
Ultrix 4.5 /bin/sh when $(TESTS) is empty.

* tests/Makefile.am (TESTS, XFAIL_TESTS): Add nobase.test.
* tests/nobase.test: New file.  Based on a bug report
from Martin Frydl <martin@idoox.com>.

* automake.in (am_install_var): Don't strip nobase_ from $X, do
this with $nodir_name only.  Use $nodir_name where appropriate.

* automake.in (handle_languages, handle_single_transform_list,
lang_c_rewrite): Use require_conf_file instead of
require_config_file to require depcomp or compile from Makefile.am.
(require_aux_file_with_line): New function, adapted from
require_conf_gile_with_line.
(require_conf_file_with_line, require_conf_file_with_conf_line):
Simplify using require_aux_file_with_line.
(require_config_file): Simplify using require_conf_file_with_conf_line.
(require_conf_file): New function.

* m4/depend.m4 (AM_DEP_TRACK): Use AC_SUBST([AMDEPBACKSLASH])
normally, what is wrong is that automake outputs a variable
definition for it, hence...
* automake.in (scan_one_autoconf_file): don't.
* m4/depout.m4 (_AM_OUTPUT_DEPENDENCY_COMMANDS): New, extracted
from...
(AM_OUTPUT_DEPENDENCY_COMMANDS): here.  Adjust.
Use AC_CONFIG_COMMANDS.
(_AM_OUTPUT_DEPENDENCY_COMMANDS): Use AS_DIRNAME and AS_MKDIR_P.

* m4/header.m4 (AM_CONFIG_HEADER): Don't use m4_patsubst.

* automake.in (&variable_conditions): Be deterministic and Perl
version independent: sort the result.
(&variable_output, &variable_pretty_output): Sort all the @conds,
not only when defaulted.
* tests/cond3.test: Adjust.

* automake.in: Formatting changes.

* aclocal.in: Use Automake::General and Automake::XFile.
Use find_configure_ac.
Output the Emacs tags for Autoconf mode selection.

* lib/COPYING, COPYING, lib/config.guess, lib/config.sub: Update
from master copies.

Do not use Autoconf internals.
* tests/dirname.test: Don't use AC_PLAIN_SCRIPT.
* m4/header.m4 (_AM_DIRNAME): Use regexp and patsubst, not
m4_regexp and m4_patsubst, since the latter are reserved for ERE
macro in GNU M4 1.5.

Regen.

* m4/cond.m4 (AM_CONDITIONAL): Don't use m4_match as Autoconf
changed its name.
