That's up to them.. I don't have access to that kind of information.  We'll 
know when a new set of headers are released.  In my experience with 
the platform, it is very rare that headers are modified in any way after 
release, until the next major version.  So my guess is that the problem 
will still exist in 8.5.

It doesn't matter so much either way, turning these defines off doesn't 
break anything.  On this platform, they are used almost exclusively to 
turn off behavior, not to enable or change behavior.  I'm perfectly willing 
to revise the patch when/if it's fixed in the headers, but I think that will 
be a while.
