-x' and `test -f' to avoid confusing users with error messages.
(AS_MKDIR_P): Invert order of separators in IFS to avoid problem
with some shells adding backslash between fields and parsing the
result for escapes.
* doc/autoconf.texi (Special Shell Variables): Document IFS.
* acgeneral.m4 (_AC_INIT_DEFAULTS_FDS): Don't check for $silent,
tie AS_MESSAGE_FD to stdout unconditionally.
(_AC_INIT_PARSE_ARGS): If $silent redirect AS_MESSAGE_FD to
/dev/null.
* tests/base.at (AC_CACHE_CHECK): New test.
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.
