2) We could avoid using gs() and get function address as byte address + byte offset. This would require extra run-time code for function pointer calls (to divide by two). It is useful in that same pointers could be used to read bytes from program memory.
Doesn't this halve the reach of code pointers? So won't it break some code that presently works on 128K AVR's?
