+       * src/location.h (boundary): Note that a line or column equal
+       to INT_MAX indicates an overflow.
+       * src/scan-gram.l: Include verify.h.  Don't include get-errno.h.
+       (rule_length_overflow, increment_rule_length, add_column_width):
+       New functions.
+       (<INITIAL>{id}, <SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'"):
+       (<SC_BRACED_CODE>"}"):
+       Use increment_rule_length rather than incrementing it by hand.
+       (adjust_location, handle_syncline): Diagnose overflow.
+       (handle_action_dollar, handle_action_at):
+       Fix bug with monstrosities like $-2147483648.
+       Remove now-unnecessary checks.
+       (scan_integer): Verify assumptions and remove now-unnecessary checks.
+       (convert_ucn_to_byte): Verify assumptions.
+       (handle_syncline): New arg LOC.  All callers changed.
+       Don't store through a value derived from char const * pointer.
+
+       * src/reader.c (grammar_rule_check): Rewrite slightly to avoid
+       GCC warnings.

+       * src/reader.c (grammar_current_rule_check): Also check that $$
+       is used.
+       Take the rule to check as argument, hence rename as...
+       (grammar_rule_check): this.
+       * src/reader.h, src/reader.c (grammar_rule_begin, grammar_rule_end):
+       Rename as...
+       (grammar_rule_begin, grammar_rule_end): these, for consistency.
+       (grammar_midrule_action, grammar_symbol_append): Now static.
+       * tests/torture.at (input): Don't rely on the default action
+       being always performed.
+       * tests/calc.at: "Set" $$ even when the action is "cut" with
+       YYERROR or other.
+       * tests/actions.at (Exotic Dollars): Instead of using unused
+       values, check that the warning is issued.
