/* Establish the initial context for the current lookahead if no initial
context is currently established.
We define a context as a snapshot of the parser stacks. We define
the initial context for a lookahead as the context in which the
parser initially examines that lookahead in order to select a
syntactic action. Thus, if the lookahead eventually proves
syntactically unacceptable (possibly in a later context reached via a
series of reductions), the initial context can be used to determine
the exact set of tokens that would be syntactically acceptable in the
lookahead's place. Moreover, it is the context after which any
further semantic actions would be erroneous because they would be
determined by a syntactically unacceptable token.
YY_LAC_ESTABLISH should be invoked when a reduction is about to be
performed in an inconsistent state (which, for the purposes of LAC,
includes consistent states that don't know they're consistent because
their default reductions have been disabled). Iff there is a
lookahead token, it should also be invoked before reporting a syntax
error. This latter case is for the sake of the debugging output.
For parse.lac=full, the implementation of YY_LAC_ESTABLISH is as
follows. If no initial context is currently established for the
current lookahead, then check if that lookahead can eventually be
shifted if syntactic actions continue from the current context.
Report a syntax error if it cannot. */

occurs when the lookahead is syntactically erroneous for the
currently established initial context, so error recovery manipulates
the parser stacks to try to find a new initial context in which the

- Don't assume there isn't a lookahead just because this state is a
