I got this to build and run, but it ran out of buffer space. :-(

I have since made good progress with flex.  The original lexer
was doing its own token buffering. I moved to using yytext, and
also changed YY_INPUT to get one character of input at a time
as lex used to do.  These two together have allowed me to make
real progress.

Performance isn't an issue, so doing one character at a time is fine.

Thanks everyone for the help.
