AIX status

[David Edelsohn]

	Let's also be clear that any system is a series of design choices
and tradeoffs.  All systems have their own peculiarities, benefits, and
drawbacks.  If someone is accustomed to and prefers one system, fine;
however, that does not make the other systems bad.  There is a large
design space to comprehend before making such claims.

	If the developers do not want to create a portable C++ library --
requiring the necessary extra infrastructure and effort, but ultimately
creating a better result for everyone -- fine.  Just say so and we can
stop all of this effort and find a different way to provide a portable C++
library for GCC.  If we are providing a portable C++ library for GCC, then
complaining about the effort to be portable on Unix-like systems across a
wide variety of markets is a waste of everyone's time and scape-goating.

	Choosing narrow, arbitrary, system-dependent cutoffs for
first-tier support is a slippery slope which likely will bite the very
people proposing it on the next round.  I find this system xenophobia very
discouraging.
