Both are correct. The default size of Integer in FPC is 2 Bytes (16 
Bit). Only if you use mode Delphi or ObjFPC the size is 4 Bytes (32 Bit) 
and there it is indeed introduced by the ObjPas unit which is 
automatically included by the compiler in these modes.

If you have the unit StrUtils included then it should work (it should be 
rtl.chm).
