* A word on the type hacks below
* o designed to minimise changes the rest of the system
* (this will be fixed in due course).
* o Assume 32 bit ints.
* top 8 bits struct no (max 255 structs)
* next 8 bits (pointer depth max 255)
* next 8 bits (special types static, private etc)
* next 8 bits (basic types)
*
* (should be done using a struct; driver should support
* a fully "distributable" type system - these will all
* be done when I work out how :-)

- 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.
- Of course, the expected token list depends on states to have
correct lookahead information, and it depends on the parser not
to perform extra reductions after fetching a lookahead from the
scanner and before detecting a syntax error. Thus, state merging
(from LALR or IELR) and default reductions corrupt the expected
token list. However, the list is correct for canonical LR with
one exception: it will still contain any token that will not be
accepted due to an error action in a later state.
