_AS_DETECT_BETTER_SHELL:
* lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
skip nonexistent directories.
(_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
only shell candidates which exist.
(AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
* lib/autotest/general.m4 (AT_INIT): No need to give three
parameters to _AS_PATH_WALK.
distinguish m4sugar macros.
* tests/tools.at (autoupdating with aclocal and m4_include):
New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
test case by Noah Misch <noah@cs.caltech.edu>.
* lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
and DUALCASE=1.
(AS_SHELL_SANITIZE): Remove DUALCASE=1.
* doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
it is set.
whether `set' quotes correctly: redirect stderr of the tested
`set', and use a subshell, for Ultrix; use `sed' instead of
`grep' for zsh `set' which may write binary output; match only
at the beginning of a line, to avoid false positives.
In order to avoid false positives by unrelated variables with
multiline content, put the dump algorithm in a subshell and
unset all variables containing newlines (except some which are
special to the shell). Warn about cache variables that are
unset.
`_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).
no file matches the glob, discard the warning, set `nullglob'.
(syntax-check): Likewise.
(sc_cast_of_x_alloc_return_value): Likewise.
(sc_cast_of_alloca_return_value, sc_error_exit_success)
(sc_prohibit_jm_in_m4, .re-list, sc_unmarked_diagnostics)
(m4-check): Likewise.
(sc_system_h_headers): Do not print rule on execution.
(sc_tight_scope): Do not fail for non-existing `src' directory.
(sc_changelog): Skip the Copyright footer.
* lib/autoconf/lang.m4: Remove trailing space.
ac_config_<foo>s again, sometimes normalized, sometimes not.
(AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS, AC_CONFIG_COMMANDS):
Do not do so here.
(_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
2005-07-25 rewrite. Noticed by Noah Misch.
| * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Call
| _AC_COMPILER_EXEEXT instead of m4_expand_once([_AC_COMPILER_EXEEXT])
| * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
| * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_TESTS): On subsequent
| calls, for a new language, only check that the compiler works.
| (AC_NO_EXECUTABLES): Change the redefinition of
| _AC_COMPILER_EXEEXT_TESTS so that on subsequent calls, it checks
| that the new language's compiler works if ac_no_link=no, and
| does nothing otherwise.
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@).
TAGS to ac_config_<foo>s.
(AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
(AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
normalizing it, consistent it with previous releases.
* tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
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.
a subdirectory subject to Cygnus `configure'.
* lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
* lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
report request when we have no AC_PACKAGE_BUGREPORT.
(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.
