part of the change from 2007-07-20.
Also:
* COPYING: Revert to GPLv2.
* COPYINGv3: New file, since some auxiliary build tools, used for
building autoconf and not installed, are GPLv3.
* Makefile.am (EXTRA_DIST): Distribute COPYINGv3.
* NEWS: Remove mention of GPLv3.
* README: Clarify situation regarding GPLv3.

Use "|", not "!".
* lib/autoconf/status.m4 (_AC_SRCDIRS) [ac_top_builddir_sub]:
[ac_dir_suffix]: Use "|", not "," as sed delimiter.
* tests/mktests.sh (as_me): Likewise.
* lib/freeze.mk (check-forbidden-patterns): Likewise.
* lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.

* doc/autoconf.texi (Shell Substitutions): Use "|", not "," in examples.
* lib/autotest/general.m4 (AT_INIT): Use "|", not "&" as sed delimiter
in the : -> $PATH_SEPARATOR transformation of $AUTOTEST_PATH. This is fine,
as long as $PATH_SEPARATOR doesn't contain "|".

* tests/mktests.sh (ac_exclude_list): Add AC_ARG_VAR.
* tests/torture.at (AC_SUBST: variable name validation): New test.

old AC_COMPUTE_INT, which now behaves like _AC_COMPUTE_INT
except the first two arguments are reversed.
* doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
(Generic Compiler Characteristics): AC_COMPUTE_INT no longer
caches nor outputs a diagnostic. Suggested by Bruno Haible.
* lib/autoconf/general.m4 (AC_CACHE_CHECK_INT): New macro,
equivalent to the old AC_COMPUTE_INT.
(AC_COMPUTE_INT): No longer caches or reports. New signature.
All uses changed to AC_CACHE_CHECK_INT.
* tests/base.at (AC_CACHE_CHECK_INT): New test.
* tests/mktests.sh (ac_exclude_lsit): Add AC_CACHE_CHECK_INT.
`_AC_' or `__AC_'. Noted by Stepan Kasal.
Update exclusion lists for the test suite to this end:
(AC_ARG_VAR): Do test this now.
(AC_REPLACE_FUNCS): This needs an argument.
(AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
(AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
(AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
lib/autoconf/specific.m4, lib/autoconf/status.m4,
lib/autoconf/types.m4, lib/autotest/general.m4,
tests/mktests.sh, tests/torture.at: White space cleanup:
remove some SPACE before TAB, or add quoting ('' or @&t@).
Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
Use 'comm' rather than N instances of grep; this also fixes a bug
whereby substrings were incorrectly matched, causing us to not
generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
(exclude_list): Exclude empty macros.
(ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
portability problems with regular expressions containing newlines.
(exclude_list, ac_exclude_list, au_exclude_list, ac_exclude_script):
Switch from grep to awk syntax.
(ac_exclude_script): Renamed from ac_exclude_egrep.
(au_exclude_script): Renamed from au_exclude_egrep.
(AC_C_RESTRICT): Likewise. Furthermore, add a function with a
typedef'ed restricted pointer, to catch a compiler bug on
HP-UX 11.x, and fix warnings so it passes with -Werror.
(_AC_PROG_CC_C99): Likewise.
Reported by Albert Chin <china@thewrittenword.com>.
* tests/mktests.sh: Do not skip AC_C_INLINE, AC_C_RESTRICT.

($(TESTSUITE_GENERATED_AT)): Use `$(srcdir)` for the benefit of
non-GNU make.
(autoconfdir, $(AUTOCONF_FILES)): Likewise.
* tests/mktests.sh: Small shell portability fixes.
* lib/autoconf/programs.m4 (AC_PATH_TOOL, AC_CHECK_TOOL,
AC_CHECK_TOOLS): Warn if a cross-tool is found without
a prefix.
(AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
AC_CHECK_TARGET_TOOLS): New macros.
* doc/autoconf.texi (Generic Programs): Document
(AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
AC_CHECK_TARGET_TOOLS, and warn for future changes
in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
AC_CHECK_TOOLS.
(Specifying Names): Document the reason for these future
behavioral changes.
* tests/mktests.sh: Do not generate tests for the
new macros.
* NEWS: Document these changes.
* doc/autoconf.texi: Avoid macros with unbraced arguments,
they make TeX hang up.
* bin/Makefile.am (edit): Handle '@configure_input@'.
(autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
(ifnames): chmod -w.
* tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
executables, not bin/ executables! Otherwise all the magic needed
to find non installed files is turned off. This caused a failure
of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
as found in its environment (sent by tests/autoreconf): pointing
to bin/autom4te that could not find its files.
* tests/mktests.sh: Force the replacement of generated files, for
the sake of "mv" program that are interactive when overwriting a
-w file.
* config/install-sh: Upgrade from CVS Automake.

AC_FUNC_WAIT3 with "-W no-obsolete".
