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