Here are some bugs and/or suggested improvements to the bison
manual.

S3.5.3. Add a note that in bison, unlike flex, the action only
applies to the last rule, eg

X: 
a|b { x_found = 1;}

x_found will only be set if the 'b' variation is foundbut not if
the 'a' variation is found.

Appendix A. Add mention of YYDEBUG and also of @n.

I'll send in patches to this effect, once the CVS source is fixed
(currently the info does not build),
