Jun 23 1998, Erwin Waterlander, DJGPP compatibilty Oct 28 1999, Erwin Waterlander, update for WIN32 console appl. Jan 3 2000, Erwin Waterlander, update for Mingw32 compiler. Jul 14 2008, Erwin Waterlander, update for OS/2. Aug 2012, Major cleanup macros: * Use only C99 predefined macros. * Use __MSDOS__ only when it's real for MS-DOS. * UNIX is not defined on OS/2 EMX (fixed tailor.h, UNIX got defined, because _BSD_SOURCE is defined with EMX (GCC on OS/2)). * Make it compile with Watcom C for OS/2. * Borland C and LCC may have been broken, because these are not supported anymore.
