Re: Regression in 2.4 ??

[Nelson Ferreira]

Attached is the .y file.
This is a part of the SXEmacs source, where we had a report of a  
build failure with bison 2.4 which we tracked down to this behavior.
The relevant files would be under modules/cl.
You can get them from http://downloads.sxemacs.org

As far as defining manually the YYSTYPE I did it by adding on line 30:

typedef int YYSTYPE;

On another .h file [cl-loop.h] I needed to define:

extern int
cl_loop_yylex(YYSTYPE*, Lisp_Object*,
              cl_loop_sentence_t*, Lisp_Object*, Lisp_Object*);

which used to work with just including the generated .h, but not  
anymore.

cl-loop-parser.y
