+/* 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.  */

+     - If this state is a consistent state with a default action, then
+       the only way this function was invoked is if the default action
+       is an error action.  In that case, don't check for expected
+       tokens because there are none.
+     - The only way there can be no lookahead present (in yychar) is if
+       this state is a consistent state with a default action.  Thus,
+       detecting the absence of a lookahead is sufficient to determine
+       that there is no unexpected or expected token to report.  In that
+       case, just report a simple "syntax error".
+     - Don't assume there isn't a lookahead just because this state is a
+       consistent state with a default action.  There might have been a
+       previous inconsistent state, consistent state with a non-default
+       action, or user semantic action that manipulated yychar.
+       In the first two cases, it might appear that the current syntax
+       error should have been detected in the previous state when yy_lac
+       was invoked.  However, at that time, there might have been a
+       different syntax error that discarded a different initial context
+       during error recovery, leaving behind the current lookahead.
