  New Revision: 54003

  https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=54003

  Log:
    * test/-ext-/float/test_nextafter.rb: In AIX,
      nextafter(+0.0,-0.0)=+0.0, and nextafter(-0.0,+0.0)=-0.0,
      but they should return -0.0 and +0.0, respectively. This is
      a known bug in nextafter(3) on AIX, so skip related tests.
