It would appear that your library doesn't distinguish negative and positive NAN 
values.
Is that true?

It seems that your library for sin and cos return small values where other
systems return zero. This code is a bit hard to follow, since it came in
a bug report, but that's what it looks like to me.

In any case, I think that for most things the version you've built should
be fine.  The tweakfld test is an old one --- if an older version of gawk
also fails on it under Interix then I don't think it's an issue.

Thanks,
