Version 1.30i.

The ISO C++ standard is extremely clear about it: stderr is
considered a macro, not a regular symbol (see table 94 `Header
<cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
Therefore std:: does not apply to it.  It still does with fprintf.
Also, s/cstdio.h/cstdio/.

+2002-01-03  Akim Demaille  <[email protected]>
+
+	* lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
+	for non system headers.
+
+2001-12-27  Paul Eggert  <[email protected]>
+
+	* src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
+	cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
+	Sparc, as they were causing more porting problems than the
+	(minor) performance improvement was worth.
+
+2001-12-22  Akim Demaille  <[email protected]>
+
+	* src/output.c (output_short_table, output_short_or_char_table):
+	Change the prototype to use `int' for array ranges: some
+	invocations do pass an int, not a short.
+	Reported by Wayne Green.
+
+2001-12-22  Akim Demaille  <[email protected]>
+
+	Some actions of web2c.y are improperly triggered.
+	Reported by Mike Castle.
+
+	* src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
+	* tests/regression.at (Web2c): Rename as...
+	(Web2c Report): this.
+	(Web2c Actions): New.

+2001-12-22  Akim Demaille  <[email protected]>
+
+	Reductions in web2c.y are improperly reported.
+	Reported by Mike Castle.
+
+	* src/conflicts.c (print_reductions): Fix.

+
+	Version 1.30h.
+
+2001-12-18  Akim Demaille  <[email protected]>
+
+	Some host fail on `assert (!"foo")', which expands to
+	((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
+	Reported by Nelson Beebee.
+
+	* src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
+	`#define it_succeeded 0' and `assert (it_succeeded)'.
+
+2001-12-17  Paul Eggert  <[email protected]>
+
+	* src/bison.simple (YYSTD): New macro.
+	(YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE, YYFPRINTF, YYSTDERR): Use
+	it to simplify macros, and fix some C++ porting problems reported
+	by Hans Aberg.
+
+	* src/output.c (output): Define YYDEBUG to 0 if it is not defined
+	and if we are not debugging.  POSIX requires this.
+	* NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document this.
+
+	* src/output.c (output_gram, output_rule_data): Do not assume that
+	the user defines YYDEBUG to a properly parenthesized expression.
+
+2001-12-15  Akim Demaille  <[email protected]>
+
+	* src/nullable.c (set_nullable): Useless rules must be skipped,
+	otherwise, since we range over their symbols, we might look at a
+	nonterminal which no longer ``exists'', i.e., it is not counted in
+	`nvars', hence we overflow our arrays.
+
+2001-12-15  Akim Demaille  <[email protected]>
+
+	* src/reader.c (copy_action): When --yacc, don't append a `;'
+	to the user action: let it fail if lacking.
+	Suggested by Arnold Robbins and Tom Tromey.
+
+2001-12-13  Akim Demaille  <[email protected]>
+
+	Version 1.30g.
+
+2001-12-13  Akim Demaille  <[email protected]>
+
+	The computation of nullable is broken: it doesn't handle empty
+	RHS's properly.
+
+	* tests/torture.at (GNU AWK Grammar): New.
+	* tests/sets.at (Nullable): New.
+	* src/nullable.c (set_nullable): Instead of blindly looping over
+	`ritems', loop over the rules, and then over their rhs's.
+
+	Work around Autotest bugs.
+
+	* src/warshall.c (bitmatrix_print): Don't use `+--+' as table
+	frame, because Autotest understand lines starting with a `+' as
+	traces from the shell.  Then, they are not processed properly.
+	Admittedly an Autotest bug, but we don't have time to wait for
+	Autotest to catch up.
+	* tests/regression.at (Broken Closure): Adjust to the new table
+	frames.
+	Move to...
+	* tests/sets.at: here.
+
+2001-12-12  Paul Eggert  <[email protected]>
+
+	* src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
+	Do not infringe on the global user namespace when using C++.
+	(YYFPRINTF, YYSTDERR): New macros, needed for the above.
+	All uses of `fprintf' and `stderr' changed.
+
+	* src/output.c (output): Do not output "#include <stdio.h>"; that
+	is bison.simple's job.  stdio.h should be included only if
+	necessary, to avoid infringing on the user name space when
+	possible.
+
+2001-12-12  Akim Demaille  <[email protected]>
+
+	* src/complain.h, src/complain.c: Remove error_one_per_line, rely
+	on that of lib/error.c.
+
+2001-12-12  Akim Demaille  <[email protected]>
+
+	Some hosts don't like `/' in includes.
+
+	* src/system.h: Include libgettext.h without qualifying the path.
+	* src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
+	$(top_srcdir).
+
+2001-12-10  Akim Demaille  <[email protected]>
+
+	Bison dumps core on bash.y.
+	Reported by Pascal Bart.
+
+	* src/warshall.c (bitmatrix_print): New.
+	(TC): Use it.
+	When performing a transitive closure R(i, j) && R(j, k) => R(i,	k),
+	j must be the outer loop.
+	* tests/regression.at (Broken Closure): New.
+
+2001-12-05  Akim Demaille  <[email protected]>
+
+	Version 1.30f.
+
+2001-12-05  Akim Demaille  <[email protected]>
+
+	* tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
+	its argument.
+	Reported by Peter Hámorský.
+
+2001-12-05  Akim Demaille  <[email protected]>
+
+	* src/conflicts.c (err_table): Remove.
+	(resolve_sr_conflict): Adjust.
+	* src/lalr.h (state_t.reduction_table, state_t.shift_table):
+	Rename as...
+	(state_t.reductions, state_t.shifts): this.
+
+2001-12-05  Akim Demaille  <[email protected]>
+
+	* src/reduce.c (reduce_grammar_tables): No longer disable the
+	removal of useless rules via CPP but via `if (0)', so that the
+	compiler still check the code is valid.
+	For instance, it should have noticed `rline' no longer exists: use
+	the `line' member of rule_t.
+	* src/gram.c (dummy, rline): Remove, unused.
+
+2001-12-05  Akim Demaille  <[email protected]>
+
+	* src/output.c (pack_vector): Use assert, not berror.
+	* src/main.c (berror): Remove, unused.
+
+2001-12-05  Akim Demaille  <[email protected]>
+
+	New experimental feature: if --verbose --trace output all the
+	items of a state, not only its kernel.
+
+	* src/print.c (print_core): If `trace_flag', then invoke closure
+	before outputting the items of the state (print_core is no longer
+	a correct name them).
+	(print_results): Invoke new_closure/free_closure if needed.
+
+2001-12-05  Akim Demaille  <[email protected]>
+
+	* src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
+	* src/closure.c, src/closure.h (itemsetsize): Rename as...
+	(nitemset): for consistency with the rest of the project.
+
+2001-12-05  Akim Demaille  <[email protected]>
+
+	* src/closure.c (print_closure): Improve.
+	(closure): Use it for printing input and output.
+
+2001-12-05  Akim Demaille  <[email protected]>
+
+	* src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
+	indexed by nonterminals.
+
+2001-12-05  Akim Demaille  <[email protected]>
+
+	* src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
+	what it was!).
+	* src/warshall.h: Remove accidental duplication of the content.
+
+2001-12-05  Akim Demaille  <[email protected]>
+
+	* src/closure.c (set_fderives): De-obfuscate.
+
+2001-12-05  Akim Demaille  <[email protected]>

+2001-12-05  Akim Demaille  <[email protected]>
+
+	* src/closure.c (set_firsts): De-obfuscate.
+
+2001-12-05  Akim Demaille  <[email protected]>
+
+	* src/output.c (action_row): De-obfuscate
+	using the good o' techniques: arrays not pointers, variable
+	locality, BITISSET, RESETBIT etc.
+
+2001-12-05  Akim Demaille  <[email protected]>
+
+	Pessimize the code to simplify it: from now on, all the states
+	have a valid SHIFTS, which NSHIFTS is possibly 0.
+
+	* src/LR0.c (shifts_new): Be global and move to..
+	* src/state.c, src/state.h: here.
+	* src/conflicts, src/lalr.c, src/output.c, src/print.c,
+	* src/print_graph: Adjust.
+
+2001-12-05  Akim Demaille  <[email protected]>
+
+	* src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
+	* src/conflicts.c: Use it.
+	Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
+	incorrectly ``simplified''.
+
+2001-12-05  Akim Demaille  <[email protected]>
+
+	* src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
+	using the good o' techniques: arrays not pointers, variable
+	locality, BITISSET, RESETBIT etc.
+
+2001-12-05  Akim Demaille  <[email protected]>
+
+	* src/state.h (SHIFT_SYMBOL): New.
+	* src/conflicts.c: Use it to deobfuscate.
+
+2001-12-05  Akim Demaille  <[email protected]>
+
+	* src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
+	(print_reductions): De-obfuscate using the good o' techniques:
+	arrays not pointers, variable locality, BITISSET.
+
+2001-12-05  Akim Demaille  <[email protected]>
+
+	* src/conflicts.c (print_reductions): Arrays, not pointers.
+	Use BITISSET.
+
+2001-12-05  Akim Demaille  <[email protected]>
+
+	* src/conflicts.c (print_reductions): Pessimize, but clarify.
+
+2001-12-05  Akim Demaille  <[email protected]>
+
+	* src/conflicts.c (print_reductions): Improve variable locality.
+
+2001-12-05  Akim Demaille  <[email protected]>
+
+	* src/conflicts.c (print_reductions): Pessimize, but clarify.
+
+2001-12-05  Akim Demaille  <[email protected]>
+
+	* src/conflicts.c (print_reductions): Improve variable locality.
+
+2001-12-05  Akim Demaille  <[email protected]>
+
+	* src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
+	* src/lalr.c: Use them.
+
+2001-12-05  Akim Demaille  <[email protected]>
+
+	* src/LR0.c (augment_automaton): Formatting changes.
+	Better variable locality.
+
+2001-12-05  Akim Demaille  <[email protected]>
+
+	* src/lalr.c (matrix_print): New.
+	(transpose): Use it.
+	Use arrays instead of pointers.
+
+2001-12-05  Akim Demaille  <[email protected]>
+
+	* src/lalr.c (maxrhs): Move to...
+	* src/gram.c, src/gram.h (ritem_longest_rhs): here.
+	* src/lalr.c (build_relations): Adjust.
+
+2001-12-05  Akim Demaille  <[email protected]>
+
+	* src/lalr.c (transpose): Free the memory allocated to the
+	argument, as it is replaced by the results by the unique caller.
+	(build_relations): Merely invoke transpose: it handles the memory
+	deallocation.
+	Improve variable locality.
+	Avoid variables used as mere abbreviations.
+	(compute_lookaheads): Use arrays instead of pointers.
+
+2001-12-05  Akim Demaille  <[email protected]>
+
+	* src/lalr.c (initialize_F): Improve variable locality.
+	Avoid variables used as mere abbreviations.
+
+2001-12-05  Akim Demaille  <[email protected]>
+
+	* src/derives.c (print_derives): Display the ruleno.
+	* src/lalr.c (initialize_F, transpose): Better variable locality
+	to improve readability.
+	Avoid variables used as mere abbreviations.
+
+2001-12-05  Akim Demaille  <[email protected]>
+
+	* src/lalr.c (traverse): Use arrays instead of pointers.
+
+2001-12-05  Akim Demaille  <[email protected]>
+
+	* src/nullable.c (set_nullable): Use a for loop to de-obfuscate
+	the handling of squeue.
+	`symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
+
+2001-12-05  Akim Demaille  <[email protected]>
+
+	Because useless nonterminals are now kept alive (instead of being
+	`destroyed'), we now sometimes examine them, and store information
+	related to them.  Hence we need to know their number, and adjust
+	memory allocations.
+
+	* src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
+	static.
+	* src/LR0.c (allocate_itemsets): The memory allocated to
+	`symbol_count' was used for two different purpose: once to count
+	the number of occurrences of each symbol, and later reassigned to
+	`shift_symbol', containing the symbol that can be shifted from a
+	given state.
+	Deobfuscate, i.e., allocate, use and free `symbol_count' here
+	only, and...
+	(new_itemsets): Allocate `shift_symbol' here.
+	(allocate_itemsets): symbol_count includes useless nonterminals.
+	Make room for them.
+	(free_storage): Use `free', not `XFREE', for pointers that cannot
+	be null.
+
+2001-12-05  Akim Demaille  <[email protected]>
+
+	* src/nullable.c (set_nullable): Deobfuscate the handling of
+	ritem.
+	`symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
+
+2001-12-05  Akim Demaille  <[email protected]>
+
+	* src/gram.c, src/gram.h (ritem_print): New.
+	* src/gram.c (dummy): Remove, now there is actual code in gram.c.
+	(This useless function was defined only to work around VMS linkers
+	that can't handle compilation units with variables only).
+	* src/reduce.c (dump_grammar): Use it to trace the construction of
+	ritem.
+
+2001-12-04  Paul Eggert  <[email protected]>
+
+	* src/bison.simple (union yyalloc): Change member names
+	to be the same as the stack names.
+	(yyparse): yyptr is now union yyalloc *, not char *.
+	(YYSTACK_RELOCATE): Likewise.  This avoids a GCC warning,
+	and may generate better code on some machines.
+	(yystpcpy): Use prototype if __STDC__ is defined, not just
+	if __cplusplus is defined.
+
+2001-11-30  Akim Demaille  <[email protected]>
+
+	* configure.in (WARNING_CFLAGS): Add -Werror when possible.
+	(CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
+	Gettext doesn't compile cleanly, and dies with -Werror.
+	* src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
+	Include WARNING_CFLAGS here.
+	* lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
+	before being defined.
+
+2001-11-30  Paul Eggert  <[email protected]>
+
+	* lib/quotearg.h (quotearg_n, quotearg_n_style):
+	First arg is int, not unsigned.
+	* lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
+	(SIZE_MAX, UINT_MAX): New macros.
+	(quotearg_n_options): Abort if N is negative.
+	Avoid overflow check on hosts where size_t is 64 bits and int
+	is 32 bits, as overflow is impossible there.
+	Fix off-by-one typo that caused unnecessary reallocation.
+
+2001-11-30  Paul Eggert  <[email protected]>
+
+	Name space cleanup in generated parser.
+
+	* doc/bison.texinfo (Bison Parser): Discuss system headers
+	and their effect on the user name space.
+
+	* src/bison.simple:
+	(YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
+	YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
+	i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
+
+	(YYSIZE_T): New macro.  Use it instead of size_t, to avoid infringing
+	on user names when possible.
+
+	(YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
+	Simplify test for whather <alloca.h> exists.
+
+	(<stdlib.h>): Include if we will use malloc, and if standard C or C++.
+
+	(<stdio.h>): Include if YYDEBUG.
+
+	(yymemcpy): Renamed from __yy_memcpy.  Do not define unless
+	! defined (yyoverflow) && ! defined (yymemcpy).
+
+	(yymemcpy, yyparse): Rename local variables as needed so that
+	they all begin with 'yy'.
+
+	(yystrlen, yystpcpy): New functions.
+
+	(YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
+	All uses changed.
+
+	(yyparse): size_t -> YYSIZE_T.  Use yystrlen and yystpcpy
+	instead of relying on string.h functions.  Use YYSTACK_ALLOC
+	and YYSTACK_FREE instead of malloc and free.
+
+2001-11-30  Akim Demaille  <[email protected]>
+
+	* src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
+	if body instead of `;' to pacify GCC's warnings.
+
+2001-11-30  Akim Demaille  <[email protected]>
+
+	Instead of mapping the LHS of unused rules to -1, keep the LHS
+	valid, but flag the rules as invalid.
+
+	* src/gram.h (rule_t): `useful' is a new member.
+	* src/print.c (print_grammar): Adjust.
+	* src/derives.c (set_derives): Likewise.
+	* src/reader.c (packgram, reduce_output): Likewise.
+	* src/reduce.c (reduce_grammar_tables): Likewise.
+	* tests/reduce.at (Underivable Rules, Useless Rules): New.
+
+2001-11-30  Akim Demaille  <[email protected]>
+
+	* src/reduce.c (reduce_output): Formatting changes.
+	* src/print.c (print_results, print_grammar): Likewise.
+	* tests/regression.at (Rule Line Numbers)
+	(Solved SR Conflicts, Unresolved SR Conflicts): Adjust.
+
+2001-11-30  Akim Demaille  <[email protected]>
+
+	* src/reduce.c (nonterminals_reduce): Instead of throwing away
+	useless nonterminals, move them at the end of the symbol arrays.
+	(reduce_output): Adjust.
+	* tests/reduce.at (Useless Nonterminals): Adjust.
+
+2001-11-30  Akim Demaille  <[email protected]>
+
+	* src/reduce.c: Various comment/formatting changes.
+	(nonterminals_reduce): New, extracted from...
+	(reduce_grammar_tables): here.
+	(reduce_grammar): Call nonterminals_reduce.
+
+2001-11-29  Paul Eggert  <[email protected]>
+
+	* src/bison.simple (YYSTACK_REALLOC): Remove.
+	(YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
+	(YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
+	New macros.
+	(union yyalloc): New type.
+	(__yy_memcpy): Last arg is size_t, not unsigned int, to remove
+	an arbitrary restriction on hosts where size_t is wider than int.
+
+	(yyparse): Don't dump core if alloca or malloc fails; instead, report
+	a parser stack overflow.  Allocate just one block of memory for all
+	three stacks, instead of allocating three blocks; this typically is
+	faster and reduces fragmentation.
+
+	Do not limit the number of items in the stack to a value that fits
+	in 'int', as this is an arbitrary limit on hosts with 64-bit
+	size_t and 32-bit int.
+
+2001-11-28  Akim Demaille  <[email protected]>
+
+	* src/LR0.c (shifts_new): New.
+	(save_shifts, insert_start_shift, augment_automaton): Use it.
+
+2001-11-28  Akim Demaille  <[email protected]>
+
+	* src/closure.c (closure): `b' and `ruleno' denote the same value:
+	keep ruleno only.
+
+2001-11-28  Akim Demaille  <[email protected]>
+
+	* src/closure.c (closure): Instead of looping over word in array
+	then bits in words, loop over bits in array.
+
+2001-11-28  Akim Demaille  <[email protected]>
+
+	* src/closure.c (closure): No longer optimize the special case
+	where all the bits of `ruleset[r]' are set to 0, to make the code
+	clearer.
+
+2001-11-28  Akim Demaille  <[email protected]>
+
+	* src/closure.c (closure): `r' and `c' are new variables, used to
+	de-obfuscate accesses to RULESET and CORE.
+
+2001-11-28  Akim Demaille  <[email protected]>
+
+	* src/reduce.c (reduce_print): Use ngettext.
+	(dump_grammar): Improve the trace accuracy.
+
+2001-11-28  Akim Demaille  <[email protected]>
+
+	* src/reduce.c (dump_grammar): Don't translate trace messages.
+
+2001-11-28  Akim Demaille  <[email protected]>
+
+	* tests/reduce.at (Useless Terminals, Useless Nonterminals): New.
+	* src/reduce.c (reduce_grammar_tables): Do not free useless tags,
+	as all tags are free'ed afterwards.
+	From Enrico Scholz.
+
+2001-11-27  Akim Demaille  <[email protected]>
+
+	* src/system.h: Use intl/libgettext.h.

+
+2001-11-27  Paul Eggert  <[email protected]>
+
+	* src/bison.simple (YYSTACK_REALLOC): Fix typo that caused us to
+	use alloca when we didn't want to, and vice versa.

+
+	* tests/torture.at (Exploding the Stack Size with Malloc):
+	s/YYSTACK_USE_ALLOCA_ALLOCA/YYSTACK_USE_ALLOCA/.
+
+2001-11-27  Akim Demaille  <[email protected]>
+
+	* src/files.c: Include error.h.

 Bison News
 ----------
 
+Changes in version 1.30i:
+
+* Use of alloca in parsers
+  If YYSTACK_USE_ALLOCA is defined to 0, then the parsers will use
+  malloc exclusively.  Since 1.29, but was not NEWS'ed.
+
+  alloca is used only when compiled with GCC, to avoid portability
+  problems as on AIX.
+
+* Bug fixes
+
+Changes in version 1.30h:
+
+* When the generated parser lacks debugging code, YYDEBUG is now 0
+  (as POSIX requires) instead of being undefined.
+
+* User Actions
+  Bison has always permitted actions such as { $$ = $1 }: it adds the
+  ending semicolon.  Now if in Yacc compatibility mode, the semicolon
+  is no longer output: one has to write { $$ = $1; }.
+
+Changes in version 1.30g:
+
+* Bug fixes
+
+* Better C++ compliance
+  The output parsers try to respect C++ namespaces.
+
+Changes in version 1.30f:
+
+* Reduced Grammars
+  Fixed bugs when reporting useless nonterminals.
+
+* 64 bit hosts
+  The parsers work properly on 64 bit hosts.
