Comment:

 I disagree; real inputs should give real outputs (like sqrt, and at least
 for functions like this where there's a "usual" range that gives real
 results). I do think that the result should be NaN instead of cephes's
 "-infinity", because it's not real there, and -infinity makes zero sense
 -- fixed that r3142.
