changelog

autoconf是一个产生可以自动配置源代码包

2006-06-23  Ralf Wildenhues  <[e-mail]>

	Version 2.60.

	* configure.ac, NEWS: Update.

2006-06-23  Ralf Wildenhues  <[e-mail]>

	* config/texinfo.tex: Sync from upstream.

	* bin/autom4te.in (handle_traces): Transform the `@S|@'
	quadrigraph correctly in traces.

	* NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
	Fix typos.

	* lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
	datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
	not defined.
	* doc/autoconf.texi (Changed Directory Variables): New node,
	to document the whole `datarootdir' business a bit better.
	* NEWS: Update.
	* tests/torture.at (datarootdir workaround): Extend test.
	Prompted by report by Alexandre Julliard.

2006-06-22  Paul Eggert  <[e-mail]>

	* lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
	when using default mode of IBM C 6 for AIX.  Problem and two-line
	fix reported by Larry Jones.

2006-06-22  Alexandre Julliard <[e-mail]>

	* lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
	about literal '${datarootdir}' if a definition is found in the
	output file.

2006-06-20  Paul Eggert  <[e-mail]>

	* NEWS: Use "M4" rather than "m4" when appropriate.
	Problem reported by Eric Blake.
	* doc/autoconf.texi: Likewise.
	Use @acronym around BSD, GCC, and GNU when appropriate.
	(Why GNU M4): Renamed from "Why GNU m4".
	(Redefined M4 Macros): Mention that Posix
	m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
	(Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
	to int.

2006-06-20  Ralf Wildenhues  <[e-mail]>

	* bin/autom4te.in (handle_output): Do not forbid the empty
	pattern.
	* tests/tools.at (autoconf: the empty token): New test.

2006-06-20  Stepan Kasal  <[e-mail]>

	* lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
	calls, so that we do not care whether they are LIFO or FIFO;
	in the m4_wrap, do not check which diversion is the topmost
	one, just check that the stack is balanced at the end.
	* lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
	base diversion forever--pop the previous diversion before
	opening the new one; consequently, remove the m4_wrap call.
	* lib/autotest/general.m4 (AT_INIT): Likewise.
	* tests/m4sugar.at: Do not use
	m4_wrap([m4_diversion_pop([..])]), for educational purposes.

2006-06-19  Paul Eggert  <[e-mail]>
	and Ralf Wildenhues  <[e-mail]>

	* NEWS: Document that m4wrap/m4_wrap might not be LIFO.
	* doc/autoconf.texi (Redefined M4 Macros): Likewise.
	Rework example of m4wrap token-pasting trouble so that it doesn't
	care whether it's LIFO or FIFO.
	Fix some "contrary to"s that are awkward in English.

2006-06-19  Ralf Wildenhues  <[e-mail]>

	* lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
	to `yes' instead of `int$1_t' if the type is found, for more
	consistent configure output (where $1 is the number of bits).
	(_AC_TYPE_UINT): Likewise for `uint$1_t'.
	Suggested by Bruno Haible.

	* lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
	needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
	with system headers.  Report by Bruno Haible.

2006-06-17  Ralf Wildenhues  <[e-mail]>

	* config/config.guess, config/config.sub: Sync from upstream.

	* bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
	in order to avoid picking up an older installed frozen m4sh.m4f.
	Besides an outdated shell startup, this could have been created
	by an earlier M4 version with incompatible frozen file format.

2006-06-16  Paul Eggert  <[e-mail]>

	* README: Recommend m4 1.4.4 instead of 1.4.3..
	* doc/autoconf.texi: Likewise.
	(Special Chars in Names): Say that $(.FOO) is portable, as
	suggested by Stepan Kasal.
	(Installation Directory Variables, Build Directories):
	(Automatic Remaking, Subdirectories, Fortran Compiler):
	(Making testsuite Scripts, Defining Directories):
	Quote variable usages better.
	(Making testsuite Scripts): Add clean-local rule to makefile
	snippet, by Eric Blake.
	(Installation Directory Variables): Fix table item font.
	Reword slightly to clarify.  Generalize advice about
	not using special characters to include all file-related
	vars, not just VPATH.
	(Special Chars in Variables): Warn about special characters in
	$(srcdir) too.
	(Assignments): Clarify default-value example as suggested by
	Ralf Wildenhues in
	<http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
	(Special Shell Variables): Note leading ./ or ../, as suggested
	by Eric Blake.
	(Limitations of Builtins): Under cd, warn about CDPATH.
	(The Make Macro MAKEFLAGS): Untabify.  Problem reported by
	Ralf Wildenhues.

2006-06-15  Ralf Wildenhues  <[e-mail]>

	* doc/autoconf.texi (Configuration Actions): Remove duplicate
	`@var', for texi2html.
	(Systemology): Some more word wrapping, for DVI output.
	(autom4te Invocation): The short option for `--melt' is `-M',
	not `-m'.

2006-06-15  Paul Eggert  <[e-mail]>

	* doc/autoconf.texi: More formatting and English tweaks,
	many suggested by Ralf Wildenhues.
	Reword to avoid "@code{...}'s" and the like, since it's ugly
	with Emacs info mode.  discontents -> woes.
	Put a few "will"s back.  time stamp -> timestamp.
	side-effect -> side effect.

2006-06-14  Paul Eggert  <[e-mail]>

	* doc/autoconf.texi (Initializing configure, Shell Substitutions):
	Warn about $@ not persisting.  Problem reported by Julien Danjou in
	<http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
	(Special Chars in Names): Renamed from Leading _ in Macro Names.
	Mention other special chars, too.

2006-06-14  Eric Blake  <[e-mail]>

	* doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.

2006-06-13  Paul Eggert  <[e-mail]>

	* doc/autoconf.texi: Some systematic minor improvements, as
	follows.  Use "makefile" when talking about makefiles
	generally (which might be named "makefile" or "Makefile" or even
	"foo.mk"), "Makefile" when talking about a specific makefile
	called "Makefile".  This unclutters the text from weird quotes
	(e.g., "`Makefile's" in info mode).  Similarly, use "@var{foo}
	values" rather than "@var{foo}s" and similar constructs containing
	"}s".  Use "Make rules" rather than "Makefile rules".  Minor
	English-language improvements.  Change the prefix "sub-" to "sub"
	and "re-" to "re".
	Put blank lines around examples more consistently.
	Avoid "rather" and "very" as intensifiers.
	Avoid "will" as an auxiliary.
	(Limitations of Make): Split this node into....
	(Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
	(Leading _ in Macro Names, Backslash-Newline-Newline):
	(Backslash-Newline Comments, Long Lines in Makefiles):
	(Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
	(obj/ and Make, make -k Status, VPATH and Make):
	(VPATH and Double-colon, $< in Explicit Rules):
	(Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
	(Make Target Lookup, Single Suffix Rules, Timestamps and Make):
	New nodes, resulting from splitup of Limitations of Make.
	All cross-references changed.  Raise the top node from
	a section to a chapter, and all subnodes accordingly.
	Redo the introductory wording to match the new organization.
	(Installation Directory Variables): Use an example that is
	closer to what Autoconf actually does.  Mention that VPATH's
	value should not contain metacharacters or white space.
	(Fortran Compiler): Fix a VPATH bug in an example.
	(Leading _ in Macro Names): Mention that this problem is no longer
	of practical concern.
	(VPATH and Make): Reword the advice to make it clearer
	that Autoconf and Automake support VPATH in non-GNU make, but
	many packages have bugs in this area.
	($< in Explicit Rules): Refer to Build Directories rather
	than using a (non-VPATH-safe) example.
	(Automatic Rule Rewriting): Mention the sort of disaster that
	can ensue with Solaris-style rule rewriting with VPATH.

2006-06-13  Ralf Wildenhues  <[e-mail]>

	* doc/install.texi (Compilers and Options): Weaken the
	suggestion to use GNU make for VPATH builds.

	* lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
	AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.

	* lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
	in regular expression.

2006-06-08  Ralf Wildenhues  <[e-mail]>

	* doc/autoconf.texi (Installation Directory Variables):
	Drop extra @samp from `@table @samp' item.
	(Limitations of Usual Tools): Comment fix.
	Do not nest @samp just to point to other table items.
	(Writing testsuite.at) <AT_CHECK>: The second argument to
	`@dvar' is already @samp'ed.
	(Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
	do not use @var in the second argument.

2006-06-07  Paul Eggert  <[e-mail]>

	* lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
	$as_shell.exe too.  Problem reported by Andreas Buening in
	<http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.

2006-06-07  Ralf Wildenhues  <[e-mail]>

	* lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
	`unused variable' compiler warning, for `-Wall -Werror'.
	Reported by Jaap Haitsma in

2006-06-06  Paul Eggert  <[e-mail]>

	* lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
	case the compiler dumps core.  Problem reported for
	OpenServer 5.0.7 by Tim Rice in
	<http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
	* lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
	Likewise.

2006-06-06  Tim Rice <[e-mail]>.

	* lib/freeze.mk: Quiet check-forbidden-patterns so the string
	"ERROR" only shows up in "make check" output if there is an
	error.

2006-06-06  Eric Blake  <[e-mail]>

	* tests/tools.at (automatically allowed tokens): Fix typo.

2006-06-05  Paul Eggert  <[e-mail]>

	* NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.

	* doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
	typically overflows on x86 CPUs, even though the C standard
	requires otherwise.

	Suggested by Eric Blake.

2006-06-05  Paul Eggert  <[e-mail]>
