Are you sure you need them?  Perhaps you will think otherwise after
reading section 17.8 of the DJGPP FAQ.

Sorry, I don't understand what are you asking here.  Could you please
describe the situation in more detail and then tell what do you mean
by ``temporarily mapping selectors and offsets'' into the ISR's data
area?

djgpptsr.c is about all there is to it.
