+
+       Remove uses of 'short int' and 'unsigned short int'.  This raises
+       some arbitrary limits.  It uses more memory but nowadays that's
+       not much of an issue.
+
+       This change does not affect the generated parsers; that's a different
+       task, as some users will want to conserve memory there.
+
+       Ideally we should use size_t to represent all object counts, and
+       something like ptrdiff_t to represent signed differences of object
+       counts; but that will require more code-cleanup than I have the
+       time to do right now.
+
+       * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
+       Use size_t, not int or short int, to count objects.
+       * src/closure.c (nritemset, closure): Likewise.
+       * src/closure.h (nritemset, closure): Likewise.
+       * src/nullable.c (nullable_compute): Likewise.
+       * src/print.c (print_core): Likewise.
+       * src/print_graph.c (print_core): Likewise.
+       * src/state.c (state_compare, state_hash): Likewise.
+       * src/state.h (struct state): Likewise.
+       * src/tables.c (default_goto, goto_actions): Likewise.
+
+       * src/gram.h (rule_number, rule): Use int, not short int.
+       * src/output.c (prepare_rules): Likewise.
+       * src/state.h (state_number, STATE_NUMBER_MAXIMUM, transitions,
+       errs, reductions): Likewise.
+       * src/symtab.h (symbol_number, SYMBOL_NUMBER_MAXIMUM, struct symbol):
+       Likewise.
+       * src/tables.c (vector_number, tally, action_number,
+       ACTION_NUMBER_MINIMUM): Likewise.
+       * src/output.c (muscle_insert_short_int_table): Remove.

+       * data/lalr1.cc: Extensive Doxygenation.
+       (error_): Rename as...
+       (error): this, since it is visible to the user.
+       Adjust callers.
+       (Parser::message): Now an automatic variable from...
+       (Parser::yyreport_syntax_error_): here.
+       * tests/actions.at, tests/calc.at, tests/regression.at: Adjust to
+       Parser::error.

+       Parenthesize rhs to avoid obscure problems with mistakes like
+       "foo$$bar = foo$1bar;".  Problem reported by twlevo at xs4all.

+       b4_rhs_location): Likewise.

+       * data/lalr1.cc (yyreport_syntax_error_): Catch up with glr.c and
+       yacc.c: be sure to stay within yycheck_.
+       * tests/actions.at: Re-enable C++ tests.
