Re: FreeVision port to GPC: helpers needed

I mean that changing the TYPE of both methods will cause other procedures to
fail, causing an incompability with FV.
Keeping the argument a untyped pointer, and then typecasting to a proctype will 
probably not work, [...]
It does work.
How does it work effectively? So something like:

procedure proc1(x:longint);

procedure proc2(x:longint);

begin
end;

begin
end;

type myproctype=procedure(x:longint);

procedure proc3(x:pointer);

begin
  myproctype(x);
end;

begin
 proc3(@proc1);
 proc3(@proc2);
end;
