Hi Ben!  A minor comment: If you know which platforms isnan is missing
on, and which platforms it results in incorrect results, that may be
useful information to add.  Also, knowing which inputs result in
incorrect output may also be useful.  If it is complicated to explain,
perhaps the self-test or m4 test is a better place for such discussions,
but I could not find any similar change for that area in your patch (but
I could have missed it).

Just an idea.
