+       * tests/actions.at: Test that stack overflow invokes destructors.
+       From Marcus Holland-Moritz.
+       * data/yacc.c (yyerrlab): Move the code that destroys the stack
+       from here....
+       (yyreturn): to here.  That way, destructors are called properly
+       even if the stack overflows, or the user calls YYACCEPT or
+       YYABORT.  Stack-overflow problem reported by Marcus Holland-Moritz.
+       (yyoverflowlab): Destroy the lookahead.
+
+2005-04-24  Paul Eggert  <eggert@cs.ucla.edu>
+
+       * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): Add more-descriptive comment.

+
+       * NEWS: Bison-generated C parsers no longer quote literal strings
+       associated with tokens.
+       * src/output.c (prepare_symbols): Don't escape strings,
+       since users don't want to see C escapes.
+       * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
+       in diagnostics.
+       * tests/input.at (Torturing the Scanner): Likewise.
+       * tests/regression.at (Token definitions, Web2c Actions): Likewise.

+
+       * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
+       the data size is known to be too small and we can't increase it.
+       This works around an HP-UX 11.00 glitch reported by Andrew Benham.

+
+       * src/parse-gram.y: Include quotearg.h.
+       (string_as_id): Quote $1 before using it as a key, since the
+       lexer no longer quotes it for us.
+       (string_content): Don't strip quotes, since lexer no longer
+       quotes it for us.
+       * src/scan-gram.l: Include quotearg.h.
+       ("\""): Omit quote.
+       ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
+       a key, since the rest of the lexer doesn't quote it.
+       * src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
+       * tests/regression.at (Token definitions): Check for backslashes
+       in token strings.
+
+       * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
+       (YYSIZE_T): Define to unsigned long int when using an older compiler.
+       (yyparse): Revamp code to generate long syntax error message, to
+       make it easier to translate, and to avoid problems with arithmetic
+       overflow.  Change "virtual memory" to "memory" in diagnostic, since
+       we don't know whether the memory is virtual.
