[fpc-pascal] Customizing tply

[Agustin Barto]

I integrated the generated parser and libs with the old code and now I
get a lot of run-time errors. I traced some of them to lexlib's
assigns of the default input and ouput so I commented out those (It's
a GUI app anyway). But then I started to get access violations. What
puzzles me is that my console based test-application worked just fine.

Right now I'm still using Delphi, so it's ok if you decide not to answer this.

I traced the error to this piece of the generated code:

if (yyd[yystate]=0) and (yychar=-1) then
    (* get next symbol *)
    begin
      ==> yychar := yylex; if yychar<0 then yychar := 0; <==
    end;

btw, the problem is not StreamIO, I did some extensive testing of it
and it worked fine. Besides, it doesn't seem to be an I/O related
problem, cause the parser gets to execute the action of the first
token.
