The compiler I used for the PIC processor had two memory modes, small

indicate whether the data was in ROM or RAM, for things like passing
const strings.

Unfortunately, those kinds of comparisons aren't very fruitful. Yes, technically, 24-bit pointers could be implemented on any compiler (even for PIC ;-)), but the reality of dealing with GCC's design may show that it could be difficult to implement on GCC, not because of the AVR port specifically, but in working on the common subsystems.
