Hi
I have program
procedure fun(a : integer);overload;
begin
write('integer ',a);
end;
procedure fun(a:int64);overload;
begin
write('int64 ',a);
end;
var
w : word;
begin
w:=3;
fun(w+3);
end;
Why on arch x64 program write 'int64 6' but on i386 'integer 6'

That's only part of a program, it does not compile. You may have typed it

I've presented small improve in fcpmake, witch can modified all MAKE files
in FCP project, no one must use MAKE for own project but to recompile
COMPILATOR better use it and with my patch even simpler (I think so).
