+       Be a bit more systematic about using 'abort'.
+       * lib/abitset.c (abitset_test): Remove ATTRIBUTE_UNUSED; not needed.
+       * lib/bitset.c (bitset_bytes, bitset_init, bitset_op4_cmp):
+       Put 'default: abort ();' before some other case, to satisfy older
+       pedantic compilers.
+       * lib/bitset_stats.c (bitset_stats_init): Likewise.
+       * lib/ebitset.c (ebitset_elt_find, ebitset_op3_cmp): Likewise.
+       * lib/lbitset.c (lbitset_elt_find, lbitset_op3_cmp): Likewise.
+       * src/conflicts.c (resolve_sr_conflict): Likewise.
+       * src/vcg.c (get_color_str, get_textmode_str, get_shape_str):
+       (get_decision_str, get_orientation_str, get_node_alignment_str):
+       (get_arrow_mode_str, get_crossing_type_str, get_view_str):
+       (get_linestyle_str, get_arrowstyle_str): Likewise.
+       * src/conflicts.c (resolve_sr_conflict):
+       Use a default case rather than one for the one remaining enum
+       value, to catch invalid enum values as well.
+       * src/lalr.c (set_goto_map, map_goto):
+       Prefer "assert (FOO);" to "if (!FOO) abort ();".
+       * src/nullable.c (nullable_compute, token_definitions_output):
+       Likewise.
+       * src/reader.c (packgram, reader): Likewise.
+       * src/state.c (transitions_to, state_new, state_reduction_find):
+       Likewise.
+       * src/symtab.c (symbol_user_token_number_set, symbol_make_alias):
+       (symbol_pack): Likewise.
+       * src/tables.c (conflict_row, pack_vector): Likewise.
+       * src/scan-skel.l (QPUTS): Remove unnecessary parens.
+       (BASE_QPUTS, "@output ".*\n): Remove unnecessary asserts.
+       * src/system.h: Don't include <assert.h>.
+       (assert): New macro.
+
+       * doc/bison.texinfo (Prologue, Rules, Actions, Union Decl, Action Decl):
+       (Destructor Decl, Parser Function, Pure Calling):
+       Describe rules for braces inside C code more carefully.
