[issue9920] test_cmath on atan fails on AIX

Thanks for the report.  This looks like it's probably a bug (not a particularly serious one, but worth reporting) on AIX.

The 'tanh' configure test diagnoses a similar wrong-sign-of-zero problem on FreeBSD;  it looks as though AIX is happy here---that is, 'yes' is the expected and desired result for that configure test.
