No, it isn't a bug - systemh.inc is indeed compiled in $MODE OBJFPC 
nowadays, but it defines Integer = SmallInt on line 110. Depending on 
compilation mode used for your sources (containing references to 
Integer), the definition in unit objpas (included automatically for 
modes objfpc and delphi) may override the definition in systemh.inc.
