Factor out the warning to...
(_AC_TOOL_WARN): ... this new macro; use `cross_compiling'.
* tests/local.at (AT_CHECK_MACRO_CROSS): Avoid this warning.
* tests/semantics.at (AC_C_BIGENDIAN): Likewise.
`@setcontentsaftertitlepage' for HTML.
(Writing Autoconf Macros): Likewise, insert space after `@c'.
(Leviticus, Numbers, Deuteronomy): Likewise, change `@,c' to
`@,{c}'.
`expr' away if there is nothing to do.
< --keywords >: Simplify and robustify argument handling.
Revert erroneous comment from 2005-08-23. Extend to allow
keyword negation with `!'.
Update help message. Remove broken code to prevent running
tests multiple times.
* doc/autoconf.texi (testsuite Invocation) < --keywords >:
Update and fix the documentation accordingly.
* tests/autotest.at (Keywords): Renamed to..
(Keywords and ranges): .. this. Extended to make sure negated
keywords, keywords taken from AT_SETUP arguments, and numeric
test ranges work, and that matching is case-insensitive.
allow to pass unnamed structs even in C++.
(AC_CHECK_SIZEOF): Likewise.
Also fix quoting error in `AC_MSG_FAILURE' arguments.
* tests/semantics.at (AC_CHECK_ALIGNOF struct, AC_CHECK_SIZEOF
struct): New tests for unnamed structs, each both native and
cross-compiling.
a structure inside a cast, for C++ conformance.
* lib/autoconf/types.m4 (AC_CHECK_ALIGNOF): Likewise.
Also fix quoting error in `AC_MSG_FAILURE' arguments.
like BSD, GPL, LGPL. Fix minor English typos.
(AC_STDC_HEADERS, AC_PROG_GCC_TRADITIONAL):
Mention that these macros are becoming obsolete.
(AC_STDC_HEADERS, AC_PROG_CC, AC_C_CONST, AC_C_VOLATILE):
Use more modern terminology for which standard is what.
(AC_PROG_CC): Mention gcc first, and remove obsolete references to egcs
and to ansi2knr.
(AC_PROG_CXX): Likewise.
(AC_C_PROTOTYPES, Test Functions, AC_LIBOBJ vs LIBOBJS):
Remove obsolete discussion about how to port to K&R.
(Guidelines for Test Programs): Suggest AC_HEADER_STDBOOL rather than
the obsolescent AC_HEADER_STDC.
(AC_FOO_IFELSE vs AC_TRY_FOO): Don't use #error; test programs
can't rely on it.
HP-UX sed is 99 commands, not 100.
(_AC_OUTPUT_FILES_PREPARE): Do not count the `}' of an
_AC_SUBST_FILES fragment. Separate `{' and `r' commands by
newline for portability.
* tests/torture.at (Torturing config.status): Also test 100
AC_SUBST_FILE invocations. Fix test to actually verify the
AC_CONFIG_FILES output.
* doc/autoconf.texi (Limitations of Usual Tools): Document HP-UX
command, label, and read-file `r' limits. Unify HP-UX spelling.
non-suffix rule.
($(TESTSUITE_GENERATED_AT)): Use `$(srcdir)` for the benefit of
non-GNU make.
(autoconfdir, $(AUTOCONF_FILES)): Likewise.
* tests/mktests.sh: Small shell portability fixes.
(AT_INIT): Use it, to remove arbitrary limit of 999,999 test
cases, and to work around Tru64 expr bug.
* doc/autoconf.texi (Limitations of Usual Tools): Mention Tru64
expr bug that turns the result of a regex match into a number if
possible.
test, as in `if tests; then cmd1; elif ...; else ...; fi'.
* doc/autoconf.texi (Programming in M4sh): Adjusted.
* tests/m4sh.at (AS_IF and AS_CASE): Test this. Also make sure
both macros are defun'ed so that required macros are evaluated
outside.
document m4_for, m4_foreach, m4_foreach_w, and mention
obsolete AC_FOREACH.
(Obsolete Macros): Document AC_FOREACH.
* lib/m4sugar/m4sugar.m4 (_m4_for): Fix declaration comment.
(m4_for): Fix to never loop (almost) endlessly, work correctly
with arithmetic expressions in arguments, a step of zero or
non-integer multiple of the interval, and avoid integer
overflow.
* tests/m4sugar.at: New test for m4_for, m4_foreach, and
m4_foreach_w.
