It doesn't on NetBSD-1.5/alpha -- there geometry-positive-zeros is
correct.

Sorry, that should have read:

AFAIK geometry-positive-zeros works for all NetBSD platforms - the
above difference is only for i386 + fpu.

(-bsd is for bsdi)

Thanks for the correction,

Patrick

Seems that following patch is needed.  Now It Works For Me (tm).
Giles, does the regress test now succed for you?

Your patch works for me (i386) - I'd just like to point out that it's
because we are both running on peecees with fpus and thus with libm387
loaded (else works without patch)

BTW
NetBSD 2.8 alpha   7.1 2001-03-22, Giles Lean

Shouldn't that be 1.5?

Cheers,

Patrick

    Did we decide that "most NetBSD/i386 users have fpus" in which case Marko's
patch should be applied?

Cheers,

Patrick

I'm unclear on what y'all mean by "i386 + fpu", especially since NetBSD
seems to insist on calling every Intel processor a "i386". In this case,
are you suggesting that this patch covers all NetBSD installations on
every Intel processor from i386 + fpu forward to i486, i586, etc etc? Or
is this specifically for the i386 with the 80387 coprocessor which is
how any reasonable person would interpret "i386+fpu"? ;)

History ;-)

Yes! It's simply, if the peecee type thing has a fpu (as in the sysctl
machdep.fpu_present returns 1), then libm387.so is used, and you get
differences in the (from memory 44th insignificant figure?) otherwise it
just uses libm.so and you get what is currently correct in resultmap.
