DJGPP works in protected mode, as the limit for a segment in protected mode 
is 4Gb you don't need far pointers for 64Kb ;-)

Depends on what embedded systems are you programming, if you have DOS and 
more than 1Mb djgpp is good.
DJGPP needs a DPMI host (CWSDPMI for example), heavilly use calls to DOS and 
uses the memory over the 1st Mb (under too, but with some limitations).
