  Issue #7575:  An overflow test for math.expm1 was failing on OS X 10.4/Intel,
  due to a defect in the platform's implementation of expm1.  Since the issue
  is of low severity, and appears to be fixed in OS X 10.5 and 10.6, it doesn't
  seem worth working around, so I'm just weakening the relevant test so that
  it passes on 10.4.
