arguments.
(_m4_expansion_stack): Rename as...
(m4_expansion_stack): this, and change its value: instead of using
the pushdef stack to stack each *line* of the stack, each
definition contains the whole stack. I.e., to display the whole
stack, instead of popdefing and displaying each definition, just
display the current definition.
(m4_expansion_stack_push, m4_expansion_stack_pop): New.
* tests/atspecific.m4 (AT_CHECK_AUTOCONF): Let $2 be the expected
exit status.
* tests/m4sugar.m4 (m4_require: circular dependencies): New test.
(edit).
* m4sh.m4 (AS_UNAME): Eved out from...
* acgeneral.m4 (_AC_INIT_DEFAULTS): here.
(_AC_INIT_PACKAGE): Define AC_PACKAGE_NAME.
(_AC_INIT_PARSE_ARGS): AC_SUBST the PACKAGE_ variables.
Propagate their use in the executables and the test suite.
* tests/atgeneral.m4 (PATH): Include only absolute paths.
(AT_INIT): Use AS_UNAME.
Suggested by Jim.
* acgeneral.m4 (_AC_INIT_DEFAULTS): Don't define
ac_includes_default, since...
(_AC_INCLUDES_DEFAULT_REQUIREMENTS): this new macro does.
(AC_INCLUDES_DEFAULT): Require the former when default includes
are used.
(AC_CHECK_MEMBERS, _AC_CHECK_TYPE_NEW): Don't require
AC_HEADERS_STDC, that's a job for stupendous AC_INCLUDES_DEFAULT.
* acfunctions.m4 (AC_FUNC_MALLOC): Check for stdlib.h.
`0'. Test and fix.
Reported by Assar Westerlund.
* Makefile.am (maintainer-check): New target.
* tests/Makefile.am (maintainer-check, maintainer-check-posix)
(maintainer-check-c++, expr): Likewise.
* configure.in (EXPR): Look for it.
* tests/atgeneral.m4 (AT_CHECK): Propagate $2's default value.
* tests/compile.at (Extensions): New test.
* aclang.m4 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O):
Distinguish files with or without a dot.
Be sure to read this file if you're using a non released Autoconf.
* tests/tools.at (Syntax of the scripts): The non built tools are
in `$top_srcdir', not `..'.
(autoconf --trace): When using `-i' we need the src tree, not the
build tree.
caused strange messages about AC_ARG_PROGRAM.
Reported by Jim Meyering.
* acgeneral.m4 (AC_DEFUN_ONCE): Fix the indirection to
m4_defun_once.
* m4sugar.m4 (m4_defun_once): Also define
`m4_location(MACRO-NAME)'. s/ac_warn/m4_warn/.
Use `m4_defn' to read `m4_location'.
* tests/base.at (AC_REQUIRE & AC_DEFUN_ONCE): Two new tests.
be used early.
* acgeneral.m4 (_AC_INIT_DEFAULTS): Call `_AC_INIT_PREPARE_FDS'.
(_AC_INIT_PREPARE): Don't.
(_AC_INIT_PREPARE_ENVIRONMENT, _AC_INIT_PREPARE_FDS): Rename as...
(_AC_INIT_DEFAULTS_ENVIRONMENT, _AC_INIT_DEFAULTS_FDS): these,
since they are called from `_AC_INIT_DEFAULTS', not
`_AC_INIT_PREPARE'.
(_AC_INIT_DEFAULTS_FDS): Dump `$@' in config.log, not
`$ac_configure_args' which is not computed yet.
value of the VARIABLE argument when looking for executables, we
need to set it to the correct value from AC_CHECK_TOOL when not
just passing on the incoming VARIABLE directly.
(AC_CHECK_TOOLS, AC_PATH_TOOL): Likewise.
it includes another AU defined macro.
* autoupdate.sh (input.m4:_au_defun): New macro.
(au.m4): Use it instead of inlining _au_enable/_au_disable
invocations in the definition of all these macros.
(input.m4:__au_enable, input.m4:__au_disable): New macros.
(input.m4:_au_enable, input.m4:_au_disable): Use them.
* tests/mktests.sh (update_exclude_list): Add `AC_OUTPUT'.
Running it twice in a configure.in is not valid.
Add `AC_LINK_FILES' since it requires arguments.
* tests/tools.m4 (autoupdating AC_LINK_FILES): New test.
* acgeneral.m4 (AC_SHELL_DIRNAME): When using m4 the argument
is named `$1' not `$dir'.
When using m4 you ought to quote properly.
When using m4, you should check that there are not too many shell
quotes (inside the macro itself, and where it is called).
When you do this, Autoconf, hm, works better.
(Special Shell Variables): Adjust.
(Shellology): New section. Introduce bash and zsh.
(Special Shell Variables): Some data on NULLCMD.
(Quotation Thumb Rule): Rename as
(Quotation Rule of Thumb): this.
* acgeneral.m4 (AC_SHELL_UNSET): Remove.
(AC_SHELL_UNSETENV): Rename as...
(AC_SHELL_UNSET): this.
(_AC_INIT_PREPARE_ENVIRONMENT): Prepare bash and zsh.
Adjust to AC_SHELL_UNSET.
(AC_INIT): Dispatch your arguments either to _AC_INIT_PACKAGE or
to AC_CONFIG_SRCDIR.
(AU::AC_INIT): New.
* configure.in: Adjust.
Use `#', not `dnl'.
* doc/autoconf.texi (configure.in Layout): Document the new form
of AC_INIT.
Document AC_CONFIG_SRCDIR.
(Obsolete Macros): Document the old one.
Suggested by Jim Meyering.
* acgeneral.m4 (_AC_SHELL_TMPDIR): New macro.
(_AC_OUTPUT_CONFIG_STATUS): Use it.
Use more quoted here docs to improve readability.
Compute `$me' and use it in the error messages.
Define `$configure' and `$configure_args' to avoid continuously
mixing the uses of `configure' and `config.status' evaluation in a
single line.
Define `$SHELL' and use it.
Simplify all the unjustified `[$]foo' into `$foo', the quotes
are needed only for `$[1]', `$[@]' etc.
Replace all the uses of `ac_cs_root' with files in the tmp dir of
`config.status'.
Remove a few `rm' covered by the removal of the `$tmp' dir.
Let `config.status' support `--debug'.
(_AC_INIT_PREPARE): Avoid the leading space in `ac_configure_args'.
* doc/autoconf.texi (Invoking config.status): Adjust.
section.
Document --help=short and recursive.
Split the `Directory' section into `Installation directories' for
--prefix and --exec-prefix, and all the others into `Fine tuning
of the installation directories'.
In the latter, don't repeat `in DIR', the user understands, and it
comes out better.
Default for --exec-prefix is PREFIX.
Reported by Kathryn Hargreaves.
Move --host before --build.
Fix a test on `$ac_init_help' which was not updated.
