Thanks for the link.

I'd like some explanation of why these changes are necessary before we start
adding them to Classpath.  Are we just assuming that all free implementations
will ignore NULL now?

With regards to fdlibm, there is a further upstream for this where
these changes should be made first.  fdlibm is also used by OpenJDK.
