NEWS:
Changes in version 1.30h:

* When the generated parser lacks debugging code, YYDEBUG is now 0
  (as POSIX requires) instead of being undefined.

* User Actions
  Bison has always permitted actions such as { $$ = $1 }: it adds the
  ending semicolon.  Now if in Yacc compatibility mode, the semicolon
  is no longer output: one has to write { $$ = $1; }.

        Version 1.30h.

2001-12-18  Akim Demaille  <address@hidden>

        Some host fail on `assert (!"foo")', which expands to
        ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
        Reported by Nelson Beebee.

        * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
        `#define it_succeeded 0' and `assert (it_succeeded)'.

2001-12-17  Paul Eggert  <address@hidden>

        * src/bison.simple (YYSTD): New macro.
        (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE, YYFPRINTF, YYSTDERR): Use
        it to simplify macros, and fix some C++ porting problems reported
        by Hans Aberg.

        * src/output.c (output): Define YYDEBUG to 0 if it is not defined
        and if we are not debugging.  POSIX requires this.
        * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document this.

        * src/output.c (output_gram, output_rule_data): Do not assume that
        the user defines YYDEBUG to a properly parenthesized expression.

        * src/nullable.c (set_nullable): Useless rules must be skipped,
        otherwise, since we range over their symbols, we might look at a
        nonterminal which no longer ``exists'', i.e., it is not counted in
        `nvars', hence we overflow our arrays.

2001-12-15  Akim Demaille  <address@hidden>

        * src/reader.c (copy_action): When --yacc, don't append a `;'
        to the user action: let it fail if lacking.
        Suggested by Aharon Robbins and Tom Tromey.
