AFAIK every acceptable part of the RTEMS newlib 1.11.0 patch was merged.
I just did a quick review of the last 1.11.0 patch and all that remains
that was not merged is the ARM memcpy from NetBSD with an advertising
clause (unaccceptable to merge) and a patch to libc/stdio/findfp.c
in _cleanup_r() which I would have to review to see if it was still
needed.  This fix was part of remving a leak.

I'm curious here also.  I remember lots of wide character patches
on the mailing list but nothing I thought was critical.

Yes.  The .h files are intertwined and sometimes things break.
