 | <TCXLfar.h> : Definitions and prototypes for handling explicit, typed
 | far-pointers as used internally in TCXL 5.5.
 *-------------------------------[ NOTES ]------------------------------*
 | 1) The _XxxFar() aliases take full far pointers and the _FarXxx()
 |    functions take separate segments and offsets.
 | 2) The MK_FP() and MK_FPT() macros will override system definitions
 |    and provide compiler-independence.
 | 3) MK_FPT() is *very* useful in C++, where void pointers are not
 |    usually allowed without bizarre casts.
