+ * src/lalr.c (initialize_F): Improve variable locality.
+ Avoid variables used as mere abbreviations.

+
+ * 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.

+
+ * src/lalr.c (traverse): Use arrays instead of pointers.
+
+2001-12-05 Akim Demaille <akim@epita.fr>
+
+ * 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'.

+
+ 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.

+
+ * 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 <eggert@twinsun.com>
+
+ * 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 <akim@epita.fr>
+
+ * 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.
+
+2001-11-27 Paul Eggert <eggert@twinsun.com>
+
+ * 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.
