Are you sure ?

For example, in the ppudump of the .ppu.intf file, we find the FilePos of the procedure declaration 
in the interface section

Interface definitions
----------------------
** Definition Id 0 **
Procedure definition
       Type symbol : (0) Nil
        DefOptions :
         DefStates :
       Return type : (4) Unit 0, DefId 3
          Fpu used : 0
        TypeOption : Procedure
        CallOption : MWPascal
           Options : Global
            Number : 65535
             Level : 2
             Class : (13) Nil
           Procsym : (15) SymId 33
          File Pos : 1 (17,11)
        SymOptions : Public
         Import Nr : 0
     ------ parast ------
     ------ parast ------
     Symtable datasize : 0
     Symtable alignment: 0

whereas in the ppudump of the .ppu file, we read the FilePos of the same procedure in the 
implementation section

             Level : 2
             Class : (13) Nil
           Procsym : (15) SymId 33
          File Pos : 1 (20,11)
        SymOptions : Public
         Import Nr : 0

For this unit, the checksums do match.
