 *  \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.
