[issue39396] AIX: math.nextafter(a, b) breaks AIX bot

[Michael Felt]

Michael Felt <aixtools at felt.demon.nl> added the comment:

As I said, was investigating.

a) is a bug in most AIX system libraries.
b) there is a fix, but not one I can install - as my bots and build systems run on AIX 6.1 and AIX 7.1

c) the fix is APAR IV95512 which includes fixes in the following filesets:

IV95512 shipped  nextafter(+0.0, -0.0) returns +0.0 instead of -0.0.
      bos.rte.shell 7.2.2.0
      bos.adt.prof 7.2.2.0
      bos.adt.libm 7.2.2.0

So, nothing for me "to fix" -- see https://www-01.ibm.com/support/docview.wss?uid=isg1IV95512
