  | So we're presumably ruling out AIX and Solaris,

Do you seriously believe that either of those is going to do
the work needed to upgrade to the coming version of POSIX?

Users of those are (I suspect) going to have to live with
implementations of the previous standard, forever.

There are very many changes in the coming version - the first
real update since 2008 (the intervening issued have just been
corrections and clarifications) - and this one has more changes
than the previous one had over its predecessor.
