Sorry, I don't quite follow this point.  The 1.75b documentation says
this:

   Obviously, in location tracking pure parsers, @code{yyerror} should have
   an access to the current location.  This is indeed the case for the GLR
   parsers, but not for the Yacc parser, for historical reasons.  I.e., if
   @samp{%locations %pure-parser} is passed then the prototypes for
   @code{yyerror} are:

   @example
   void yyerror (const char *msg);                 /* Yacc parsers.  */
   void yyerror (YYLTYPE *locp, const char *msg);  /* GLR parsers.   */
   @end example

so for yacc parsers, the documentation says yyerror takes only one
argument.  Perhaps you were looking at a different part of the
documentation?
