probable error

[Angelo Borsotti]

Hello,

I was having a look to the Bison sources, in particular to gram.h, where the
internal
representation of the grammar is described. This file tells that the array
RULES
holds one element for each rule, starting at index 1, which is that of an
enclosing
rule added automatically by Bison. Index 0 is unused.
However, in file gram.c, grammar_dump visits that array from index 0
(included).
Is this an error?

Thank you
