That's why fpc has this in ctypes:

{$ifdef cpu64}
  clong                  = int64;              pclong                 = ^clong;
  cslong                 = int64;              pcslong                = ^cslong;
  culong                 = qword;              pculong                = ^culong;
  clong                  = longint;            pclong                 = ^clong;
  cslong                 = longint;            pcslong                = ^cslong;
  culong                 = cardinal;           pculong                = ^culong;
