Ok. This is a Big Politic. May be yacc is better, but this doesn't mean
that "bad" bison in FreeBSD distribution can contain bug.
Try this (I suppose bison-1.25):
bison test.y && cc -c test.tab.c
===> Start test.y
%{
#define YYPARSE_PARAM param
%}
%token T_STRING
%%
input:
| input T_STRING
;
%%
===> End test.y
Can you compile this?
Here's the patch:
