[Bro-Dev] Bro script parser: shift/reduce conflicts.

[Gregor Maier]

Hi,

The bro policy script parser, parse.y has 71 shift/reduce conflicts.
(Which are resolved by bison by always choosing shift). This results in
bison issuing a warning.

Presumably these 71 conflicts are all fine and expected. So I would add
a %expect 71 clause the parse.y. This will make bison expect 71
shift/reduce conflicts. If the number differs, then bison will exit with
an error (and make exit with an error). If the number matches, bison
will be silent.

Question: are there any reason to not use this?
