+
+	Do not create a temporary file, as that involves security and
+	cleanup headaches.  Instead, use a pair of pipes.
+	Derived from a suggestion by Florian Krohm.
+	* lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
+	* lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.

+	* m4/Makefile.am (EXTRA_DIST): Remove mkstemp.m4.  Add subpipe.m4.
+	* po/POTFILES.in: Add lib/subpipe.c.
+	* src/output.c: Include "subpipe.h".
+	(m4_invoke): Remove decl.
+	(scan_skel): New decl.
+	(output_skeleton): Use pipe rather than temporary file for m4 input.
+	Check that m4sugar.m4 is readable, to avoid deadlock.
+	Check for pipe I/O error.
+	* src/scan-skel.l (readpipe): Remove decl.
+	(scan_skel): New function, to be used in place of m4_invoke.
+	Read from stream rather than file.
+
+	* lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
+	float, as this generates a warning on Solaris 8 + GCC 3.2 with
+	--enable-gcc-warnings.  Instead, divide into 1.0 rather than 1;
+	this generates a more-accurate value anyway.
+
+	* lib/timevar.c (timervar_accumulate): Rename locals to
+	avoid confusion with similarly-named more-global.
+	* src/muscle_tab.c (muscle_pair_list_grow): Likewise.
+
+	* src/output.c (prepare): Use xstrdup to convert char const *
+	to char *, to avoid GCC warning.
+
+2002-10-19  Akim Demaille  <akim@epita.fr>
+
+	* tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
+	LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
+	Use them to have `calc.y' ready for %pure-parser.
+	* data/yacc.c (YYLEX): Pass a yylex return type to
+	b4_c_function_call.
+
+2002-10-19  Akim Demaille  <akim@epita.fr>

+	(muscle_insert, muscle_find): Rename `pair' as `probe'.
+	* src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused.
+	(muscle_entry_s): The `value' member is no longer const.
+	Adjust all dependencies.
+	* src/muscle_tab.c (muscle_init): Adjust: use
+	MUSCLE_INSERT_STRING.
+	Initialize the obstack earlier.
+	* src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
+	(muscle_pair_list_grow): New.
+	* data/c.m4 (b4_c_function_call, b4_c_args): New.
+	* data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.
+	* tests/calc.at: Use %locations, not --locations.
+	(AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
+
+2002-10-19  Akim Demaille  <akim@epita.fr>
+
+	* src/getargs.c (usage): Take status as argument and exit
+	accordingly.
+	Report the traditional `Try ... --help' message when status != 0.
+	(usage, version): Don't take a FILE * as arg, it is pointless.
+	(getargs): When there is an incorrect number of arguments, make it
+	an error, and report it GNUlically thanks to `usage ()'.
+
+2002-10-18  Paul Eggert  <eggert@twinsun.com>
+
+	* data/glr.c (yyreportParseError): Don't assume that sprintf
+	yields the length of the printed string, as this is not true
+	on SunOS 4.1.4.  Reported by Peter Klein.
+
+	* tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
+	* tests/conflicts.at (%nonassoc and eof): Likewise.
+	Fixes SunOS 4.1.4 test failure reported by Peter Klein.
+
+2002-10-17  Akim Demaille  <akim@epita.fr>
+
+	* src/getargs.h (trace_e): Add trace_scan, and trace_parse.

+	Standardize error messages.
+	And s/@prec/%prec/!
+	(reader): Use trace_flag to enable scanner/parser debugging,
+	instead of an adhoc scheme.
+	* src/scan-gram.l: Remove trailing debugging code.
+
+2002-10-16  Paul Eggert  <eggert@twinsun.com>
+
+	* src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
+	MUSCLE_TAB_H.
+
+	* NEWS: Officially drop support for building Bison with K&R C,
+	since it didn't work anyway and it's not worth worrying about.
+	* Makefile.maint (wget_files): Remove ansi2knr.c.
+	(ansi2knr.c-url_prefix): Remove.
+	* lib/.cvsignore: Remove ansi2knr, ansi2knr.*.
+	* lib/Makefile.am (AUTOMAKE_OPTIONS): Remove.
+	* src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
+
+2002-10-15  Paul Eggert  <eggert@twinsun.com>
+
+	Stop using the "enum_" trick for K&R-style function definitions;
+	it confused me, and I was the author!  Instead, assume that people
+	who want to use K&R C compilers (when using these modules in GCC,
+	perhaps?) will run ansi2knr.
+
+	* lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
