No support for non-ELF, aka AIX

else figure that stuff out.
I've started to take a look at Darwin [sjlj.S] - and I have a feeling
that it's going to be nearly 'change every line' - (our asm syntax is
ancient) -
so probably, in this case, better to have a separate file (but will
try to get to a working version before making that judgement finally).
I presume that w should treat this as a normal prologue - and it looks
very much like "save the world" - so I have a question:
is there any reason that we should avoid using out-of-line saves in
this specific case?
