Bug

Hello,

I've found bug in bison 2.1. I'm using Windows and I can not test this 
with new version 2.3, because I can't find 2.3 executables for windows.
I've use bison for much larger file, but this is reduced sample to 
indicate a problem.

b.y:
--------------------------------
%%

Crlf       : '\n'          { }
            ;
--------------------------------

Command
    bison -v -d b.y -ob.c
produces b.c file, which fails to compile. The reason of failure is this 
part of code:
--------------------------------

/*----------.
| yyparse.  |
`----------*/

#ifdef YYPARSE_PARAM
# if defined (__STDC__) || defined (__cplusplus)
int yyparse (void *YYPARSE_PARAM)
# else
int yyparse (YYPARSE_PARAM)

Thanks for the report.  This is fixed as of 2.2.

Re: %destructor doesn't destruct what can be destructed by user actions

Thanks.  I committed the following to fix that and some other typos.

Thanks.  That's already fixed in CVS.
