      fix tsman compiler warning (unary minus applied to unsigned: result still unsigned)
      
      <stewart> jonas: in tsman.hpp, Tablespace_client::alloc_extent(Local_key*), the error path: "return -req->reply.errorCode;" generates a warning: "unary minus operator applied to unsigned type, result still unsigned". I gather what it should be is a cast to int and then apply - ?
      <stewart> jonas: (also in free_extent() and alloc_page_from_extent() )
      <jonas> stewart: yes, something like that
      <jonas> windows compiler ?
      <stewart> jonas: yes
       jonas: any opportunity for this to cause real bug?
      <jonas> na
