AC_OUTPUT over quotes too: stop that.
Reported by Martin Buchholz.

`Setup'.
Rename as `Notices'.
Document AC_COPYRIGHT.
Don't give false reasons for placing AC_REVISION before AC_INIT,
the place no longer matters.

failed experiment.
Merge all the var=val AC_SUBST(var) into AC_SUBST(var, val).
(AC_SUBST): Implement support for 2nd arg.

Defines a macro in `autoupdate::' with all the required wrapping
for `autoupdate'.
(AU_DEFUN): Use it.
(AC_OUTPUT): When dispatching your arguments, use ifval, not
ifset!
Dispath actions to AC_CONFIG_COMMANDS not AC_OUTPUT_COMMANDS, to
avoid unneeded warnings for obsolete use of AC_OUTPUT_COMMANDS.

AC_CONFIG_COMMANDS.
(AC_OUTPUT_COMMANDS_CNT): New variable, declared both in
`autoconf::' and `autoupdate::'.

there are to avoid spurious `run autoupdate' messages.
* doc/autoconf.texi (Libraries): Document the changes.
* acgeneral.m4 (_AC_CONFIG_COMMANDS_INIT): New macro which will
collect the `INIT-CMDS'.
(AC_CONFIG_COMMANDS, AC_CONFIG_LINKS, AC_CONFIG_HEADERS,
AC_CONFIG_FILES): Use it, and also temporarily divert to -1
instead of spamming dnl everywhere.
(AC_OUTPUT_CONFIG_STATUS): Make sure to output the INIT-CMDS
before the other sections, it'd be a pity to initialize after the
use :).
* doc/autoconf.texi (Configuration Actions): New section,
documenting the common behavior of AC_CONFIG_FILES,

Disable the name spaces `autoconf', and `libm4'. Disable libm4.
* Makefile.am: Tuned to support the changes above.
* autoupdate.sh: Model after autoconf.sh.
Can run on several files at once (for instance m4/*.m4).
Don't touch files that are up to date.
Run m4 on autoupdate.m4f instead of playing with sed.
Use AU_DEFUN.
* acgeneral.m4 (AC_LINK_FILES, AC_ENABLE, AC_WITH): Use AU_DEFUN,
remove the call to AC_OBSOLETE.
* acspecific.m4 (AC_CYGWIN32): Likewise.
* acoldnames.m4: Replaced all the definitions via `define' or
`AC_DEFUN' to use `AU_DEFUN'.
(Invoking autoconf): A better help on --trace.
(Defining Symbols): Advocate a proper use of the quotes in m4
code, including if the quotes are sometimes useless. It is bad,
very bad not to quote properly, so quote all the examples
properly.
(Cache Files): Use a unary call to define, instead of an empty
$2.
(Using System Type): Watch out TeX wrapping.
(Pretty Help Strings): Don't give too long a snippet of --help.
Promote the coding style of Autoconf. Quote properly.

and #undef over #define in templates.
* acspecific.m4 (AC_DECL_SYS_SIGLIST, AC_FUNC_MMAP,
AC_FUNC_SETPGRP, AC_FUNC_VFORK, AC_FUNC_SELECT_ARGTYPES): Use #if,
not #ifdef and #ifndef, indent CPP directives.
test.
* acgeneral.m4 (AC_CHECK_SIZEOF): Don't over quote $1, some []
were left in the C code, and had the macro fail.

exceptions.
(AT_CHECK_DEFINES): New macro, to check the content of config.h.
* tests/semantics.m4: All the tests are updated to use
AT_CHECK_DEFINES.
Test AC_CHECK_SIZEOF, AC_CHECK_HEADERS, and AC_CHECK_FUNCS.
for it. Just quote properly!
condition out the test case if __cpluscplus.
AC_REQUIRE AC_PROG_CC_STDC.
Fix slightly the display of the result (formerly the first run
says `none needed', and later, because of the cache `no').
(AC_C_INLINE, AC_C_VOLATILE): AC_REQUIRE AC_PROG_CC_STDC.
* doc/autoconf.texi (AC_C_CONST): Give a few hints on the
motivation for trusting the C++ compilers.
* acgeneral.m4 (AC_CHECK_MEMBER): It is not smart to define
ac_Foo, and use AC_Foo. Got rid of AC_Member_Aggregate and
AC_Member_Member which were complicating more than simplifying.
(AC_CHECK_DECLS): Use m4 lists.
(AC_CHECK_TYPES): A comma was missing.
* autoheader.m4: (AC_CHECK_DECLS): Use m4 lists.

verify that the tests are positive and negative when appropriate.
Test AC_CHECK_MEMBERS, AC_CHECK_DECLS and AC_CHECK_TYPES.
extern software (so that the test suite doesn't fail on them).
* acgeneral.m4 (AC_MSG_ERROR, AC_MSG_ERROR_UNQUOTED): Allow an
optional $2: exit status.
* doc/autoconf.texi: Document.
* acspecific.m4 (AC_PROG_CC_WORKS, PROG_CXX_WORKS,
AC_PROG_F77_WORKS): Exit 77 if the compiler does not work.
Introduce a new style of testing, independent from DejaGNU.
Introduce the logistics.

tests/Makefile.
* m4/atconfig.m4: New file.
* m4/Makefile.am: Adjusted.
* aclocal.m4: Include atconfig.m4.
* Makefile.am: Adjusted.
* tests/Makefile.am: New file.
* tests/atgeneral.m4: Likewise.
* tests/atconfig.in: Likewise.
Write tests.
* tests/syntax.m4: New file, in charge of checking the validity of
the sh code produced by the macros defined in acspecific.m4.
acgeneral.m4 is not checked here, because these macros require
arguments.
* tests/suite.m4: New file. Run syntax.m4.
A test suite will be introduced which tries to run all the
specific macros, but hasbeen'd macro make configure die with bad
exit status. So we wish to distinguish live macros from defunct
macros at the moment they are AC_DEFUN'd, not in their body. Hm,
defunct, defunct... Hey! That's a good name!
* acgeneral.m4 (AC_DEFUNCT): New macro, comparable to AC_DEFUN,
but for macros which are no longer defined. Replaces AC_HASBEEN.
(AC_HASBEEN): Defunct. Well, removed in fact.
(AC_HAVE_LIBRARY): Don't use AC_DEFUN and AC_HASBEEN, just
AC_DEFUNCT.
* acspecific.m4 (AC_UNISTD_H, AC_USG, AC_MEMORY_H, AC_DIR_HEADER,
AC_INT_16_BITS, AC_LONG_64_BITS): Likewise.
(AC_XENIX_DIR): It was defunct even before I declared it was: was
depending upon AC_DIR_HEADER which is defunct. So AC_DEFUNCT'ed
now.
(AC_DYNIX_SEQ, AC_IRIX_SUN, AC_SCO_INTL): While we're here, you
too are defunct now.
* autoconf.texi (Obsolete Macros): Replace the documentation of
AC_HASBEEN with that of AC_DEFUNCT.
Be kind to Automake: list the arguments of selected macros
(for instance AC_SUBST will list each variable which may be
substitued).
* autoconf.sh (--trace, --output): New options.
Implement tracing of macros.
trap also on 0, so that there is no need to rm here and there.
* autoconf.texi (Output): Document --trace and --output.
Clean up the macros for testing members of aggregates.
* acgeneral.m4 (AC_CHECK_MEMBER): FATAL if $1 has no dot in it.
Use AC_INCLUDE_DEFAULTS.
(AC_C_STRUCT_MEMBER): Removed.
* acspecific.m4 (AC_STRUCT_TIMEZONE): Adapted to AC_CHECK_MEMBERS.
(AC_STRUCT_ST_BLKSIZE, AC_STRUCT_ST_RDEV): Adapted to
AC_CHECK_MEMBERS and obsoleted.
(AC_STRUCT_ST_BLOCKS): Adapted to AC_CHECK_MEMBERS.
* autoconf.texi (AC_STRUCT_ST_BLKSIZE, HAVE_STRUCT_STAT_ST_RDEV):
Explain they are obsoleted, and how to migrate.
(AC_STRUCT_ST_BLOCKS, AC_STRUCT_TIMEZONE): Explain that the
AC_DEFINE changed (but the former #defines remain defined
currently).
(AC_C_STRUCT_MEMBER): Removed, replaced by the definitions of
AC_CHECK_MEMBER and AC_CHECK_MEMBERS.
Install a uniform set of default includes.
* acgeneral.m4 (AC_INCLUDES_DEFAULT): New macro. Expands in its
argument if non empty, otherwise a default list of includes.
(AC_CHECK_DECL, AC_CHECK_TYPE_INTERNAL): Use AC_INCLUDES_DEFAULT.
* autoconf.texi: Adjusted.
Fix a bit of the brokenness of AC_CHECK_TYPE.
* acgeneral.m4 (AC_CHECK_TYPE_INTERNAL): New macro, inspired from
the former AC_CHECK_TYPE. This macro is exactly the one that
ought to be named AC_CHECK_TYPE: it just checks, and executes user
actions. In the future, this macro ought to be renamed
AC_CHECK_TYPE.
There is a big difference with the former AC_CHECK_TYPE: instead
of grepping in the headers, it tries to compile a variable
declaration. This is both safer, slower, and better, since now we
can check for compiler types (e.g., unsigned long long).
(AC_CHECK_TYPES): The looping and AC_DEFINEing version of the
previous macro. Uses m4 loops.
(AC_CHECK_TYPE): Reimplemented on top of AC_CHECK_TYPE_INTERNAL.
* autoheader.m4 (AH_CHECK_TYPE, AH_CHECK_TYPES): New macros,
hooked.
* autoconf.texi (@ovar): New macro, for optional variables.
(Generic Typedefs): Document AC_CHECK_TYPES.
* autoheader.texi: (AH_CHECK_TYPE, AH_CHECK_TYPES): New macros.
(Epilogue): Hooks them.
Create man pages for the executables.
* Makefile.am (SUBDIRS): Add `man' and prepend `.' so that
executables be built before help2man is run.
* configure.in (AC_OUTPUT): Add man/Makefile.
AC_MSG_ERROR, not AC_ERROR.
Check for missing help2man.
* man/Makefile.am: New file.
* man/autoconf.x: Likewise.
* man/autoreconf.x: Likewise.
* man/autoheader.x: Likewise.
* man/autoscan.x: Likewise.
* man/autoupdate.x: Likewise.
* man/ifnames.x: Likewise.
* man/common.x: Likewise.
* acgeneral.m4 (AC_COMPILE_CHECK, AC_TRY_COMPILE,
AC_TRY_RUN_NATIVE, AC_OUTPUT_CONFIG_STATUS): Use @PND@ instead of
[#]: it looses the editors that try to match the pairs of (), []
etc.
Formatting changes.
* acspecific.m4: Formatting changes.
