I'm trying to solve that one :-) So, here's an updated patch with
several improvements:
- parser now only uses some additional info from scanner, it doesn't
do any modification to scanner internals
- full backward compatibility: problematic else inside case is
correctly recognized (weather it is part of last if statement or part
of case, including nested if/else-s)
- modified fpc can successfully recompile trunk versions of fpc and
lazarus (as well as projects I work on) and everything seems to work
fine
- there is also test program, but it uses ordinary Writeln-s, still
need to see how convert that to true fpc test

Due to deadlines I have these days, I wont have time to work more on
this. After that, if there is good will to accept this patch, I will
gladly take some time to make tests and do any modifications needed.

If not, there is another thing I badly need - generics of records, so
I'll try to make them usable (before, as Florian said in ticket we
"bite the bullet and support methods and operators inside records
:/").

Regards,
Aleksa
