The native compiler defines _SCO_ELF when generating elf and there are
(stupidly) enough apps that look at it that we sort of have to set it.

Yes, it is, as evidenced by the horror that is sco5.h.

I've concluded the same.  I think we're deluding ourselves that the
current GCC *really* works on some of the systems we have in the
configury.  This is why I'm more interested in yanking the remaining
crumbs of COFF support out of sco5.h than spending either your time or
mine in pretending to make it work.

I guess I should get more aggressive about cleaning it out so that
it doesn't cause further distractions.  I'll take a shot at it this
weekend.

Is there anybody left in i386 land on the targets that reasonably expect
to run GCC that isn't using a.out (some of the BSD guys) or ELF?

For all those people running Nextstep on a 386 or a Sun 386i...


So, Stan, I'm quite happy to treat the sco5 & i386 pieces of your patch
as a separate piece of business and let you focus on scratching your
immediate itch.

Thanx!
