I haven't examined it. When the branch maintainers consider it ready to
merge I hope a proposal along the lines of the DFP one
<http://gcc.gnu.org/ml/gcc/2005-11/msg01128.html> will be posted (see also
subsequent discussion in that thread, and on the submitted patches).

N1169 is the current version, with various defects addressed relative to
the published TR18037 but has not yet been published as a new revision of
the TR because of ISO bureaucracy. (To quote the draft London minutes,
"TR 18037 (embedded) has had all defects addressed. SC 22 secretariat is
requiring a NWI ballot for revising this, which is against the JTC 1
procedures.")
If any of this is included in (an Annex to) C1x, it remains to be seen if
the committee will follow the expressed principle of standardising
existing practice without changing it incompatibly. If it just moves from
being a TR to being an IS, I wouldn't expect problems with changes there.
