twlevo asked the following question:
Is ]b4_pre_prologue[ different in yacc mode?
Try the program at the end of this message with and without the
`%glr-parser' line.
is this correct?
Thanks.
line 177 glr.c, line 170 yacc.c ]b4_pre_prologue[
--------
/* */
%glr-parser
%{
/*
* pre prologue copied in y.tab.h file
* at GLR parser mode and `bison -d'
* option is used.
*
* but not copied at yacc parser mode.

#include <stdio.h>
