Sorry, nack.  yyerror() is provided for bison's convenience and is
defined by that interface to be void yyerror(const char *s).  We just
use it explicitly because it happens to be there.

Yes, I know it's unlikely that bison would supply a string with format
specifiers which would mess things up but I'm still not comfortable
changing the signature when there's no need.  If you want a varargs
error printing function, define and use one (well, if srcpos_error()
isn't close enough) instead of yyerror().
