+
+ 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.
+ * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.
+ (BISON_PREREQ_SUBPIPE): Add.
+ * lib/Makefile.am (libbison_a_SOURCES): Remove readpipe.c.
+ Add subpipe.h, subpipe.c.
+ * 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>
+
+ Prototype support of %lex-param and %parse-param.
+
+ * src/parse-gram.y: Add the definition of the %lex-param and
+ %parse-param tokens, plus their rules.
+ Drop the `_' version of %glr-parser.
+ Add the "," token.
+ * src/scan-gram.l (INITIAL): Scan them.
+ * src/muscle_tab.c: Comment changes.
+ (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.
