+/* Establish the initial context for the current lookahead if no initial

+
+   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.  */
