[fpc-pascal] Re: fcl-passrc package question about source file and line number info

Hm, it's still failing for me.

Here's what I get with test_parser from examples given this input:

===================================================
unit timelib;

{$mode objfpc}{$H+}

interface

implementation


procedure SmonthToCmonth (const sMonth : array of char;
                          const stDex  : longword;
                          out   cVal   : longword);
begin
  case sMonth[stDex] of
    'J' : cVal := 0;
  end;
end;

end.
===================================================

Here's the program output:

$ ./test_parser timelib.pas
Unit timelib;

Interface


Implementation


Procedure SmonthToCmonth(const sMonth: Array of Char; const stDex:
LongWord; out cVal: LongWord);
begin
 case sMonth[stDex] of
   'J':  cVal:= 0;
 end;
end;

end.

I'm doing it in Linux compiling for x86_64. There wouldn't be any
problem with me using this package source (pastree, paswrite, pparser,
pscanner) with FPC 2.6.0 would there? I am using FPC 2.6.0, but just
compiling this one package from svn in trunk separately.
