That's the section number I get via make bison.pdf in doc.
It's titled "A Pure (Reentrant) Parser" and the first paragrah's first
sentence begins with "A reentrant program is one which does not alter
in the course of execution".  The section has a reference to yyerror
but makes no mention of a change in calling convention for yyerror.

Certainly 1.33 and IIRC earlier versions had the ability to generate
reentrant parsers (though with a mechanism different than a %-option)
with additional parameters but with no change to the yyerror calling
convention.  Indeed, the mechanisms used in those versions still appear
to work with 1.75b in lieu of %parse-param (which is incompatible with
earlier versions of bison).
