You can use #defines to make it pretty:

#define far __attribute__((mode(SI)))

typedef void (* far ifunc)();
extern ifunc ivects[];

I think you'll find that implementing this is much more of a project
that what I need long/short pointers for.  You want multiple *default*
pointer sizes; I just want an exception that the programmer can use
for odd cases.
