--- Comment #1 from stsp at list.ru ---
This patch:
can be used as a reference of what have to be
changed to port existing code to elf.
They removed "wrt", "SEG", "group".
Did some tricks with "class". Replaced "jmp far func" with
"jmp far DGROUP:func" etc. This patch clearly shows the
needed mapping.

My question is: does this all really need an elf extensions?
Because to me it looks that these things can be
implemented on an nasm level. For example "wrt"
just seems to involve the different seg/off calculus -
does it really need an elf extension?
"jmp far sym" vs "jmp far DGROUP:sym" is just a
way of adding the default segment to jmp. Can't
this easily be solved on a nasm level? Etc.
