I don't think there's really so much of a difference between your proposal
and the current effect of the farpeek/farpoke functions (which might
better be called 'assembler macros' anyway).

And in what way would you implement a limitation of this feature to expert
users? After all, the change you suggest would require quite a bit of
modification to gcc itself, a thing DJ always tried to avoid, and with
good reason, IMHO.

They may not exactly *need* it, but they'll see it, and then they
*will* use it, wether necessary or not. And then they'll be confused,
flooding us with questions about them.
