You don't need these at all for the purposes they are used in 16-bit DOS 
compilers.  DJGPP generates 32-bit code for flat address space, where you 
don't have to worry about memory segmentation, because the segment 
registers don't change their values (well, almost).  The only case when 
you'd need to know about `far pointers' is when you have to access 
certain specific absolute addresses, like the video memory.  Read chapter 
18 of the DJGPP FAQ list (available as v2/faq200b.zip from the same place 
you get DJGPP) for more details on this.
