+ Clean up yacc.c a little.

+ whitespace more consistent. For the main parse function
+ comment, instead of saying "yyparse or yypush_parse", say either
+ "yyparse" or "yypush_parse" depending on which it actually is.

+ * doc/bison.texinfo (Decl Summary): Document complaint, and
+ improve %define documentation a little otherwise.

+ Fix gcc 3.4.4 shadowing warning reported by Eric Blake.
+ See
+ <http://lists.gnu.org/archive/html/bison-patches/2009-08/msg00093.html>.
+ * src/scan-code.h (code_props_rule_action_init): Rename
+ named_ref arg to name so it doesn't shadow named_ref type. This
+ makes it consistent with the function definition in scan-code.l
+ anyway.
