+
+       %parse-param and %lex-param now take just one argument, the
+       declaration; the argument name is deduced from the declaration.
+
+       * doc/bison.texinfo (Parser Function, Pure Calling, Error
+       Reporting, Table of Symbols): Document this.
+       * src/parse-gram.y (add_param): New function.
+       (COMMA): Remove.
+       (declaration): Implement new rule for %parse-param and %lex-param.
+       * src/scan-gram.l: "," now elicits a warning, rather than being
+       a token; this is more compatible with byacc.
+       * tests/calc.at (Simple LALR Calculator): Adopt new convention.

+
+       Rename identifiers to avoid real and potential collisions.
+
+       * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
+       to avoid collision with lex macro described by Bruce Lilly in
+       <http://mail.gnu.org/pipermail/bug-bison/2002-November/001929.html>.
+       * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
+       * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
+       * src/parse-gram.y (print_token_value): Renamed from yyprint.
+       All uses changed.
+       (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove.  All uses changed.
+       The name "yycontrol" violates the name space rules, and this stuff
+       wasn't being used anyway.
+       (input): Remove action; this stuff wasn't being used.
+       (gram_error): Rename local variable yylloc -> loc.
+       * src/reader.h (struct gram_control_s, gram_control_t): Remove.
+       (YY_DECL): Don't use "yy" at start of local variables.
+       All uses changed, e.g., yylloc -> loc.
+       * src/scan-gram.l (STEP): Renamed from YY_STEP.  All uses changed.
+       (STRING_GROW): Renamed from YY_OBS_GROW.  All uses changed.
+       (STRING_FINISH): Renamed from YY_OBS_FINISH.  All uses changed.
+       (STRING_FREE): Renamed from YY_OBS_FREE.  All uses changed.
+
+       * src/parse-gram.y (gram_error): loc is now const *.
+       * src/reader.h (gram_error): Likewise.
