They are very interesting indeed! Thank you for your
efforts in clearing this out.

Currently, this is what I wrote about the issue in the
Boost.MultiIndex docs:

http://tinyurl.com/43bfy

I'll try to rewrite it according to your explanations.
(If you feel like providing this paragraph to me, or even
changing the doc in the CVS yourself, be my guest; I'm
no Unix expert and much of this babble sounds like Greek
to me.)

As for the source code of mips-tfile.c, do you know
if it is under control of the GCC folks? If so, maybe
we can file a request that this issue be addressed
in GCC 3.4.x.
