+/** \file unixcompat.h
+ *  \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.
