  4. * This header file collects differences between the various Unix
  5. * variants that are supported by the Midnight Commander and provides
  6. * replacement routines if they are not natively available.
  7. * The major/minor macros are not specified in SUSv3, so we can only hope
  8. * they are provided by the operating system or emulate it.
