+
+ 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.
