Sorry I did not reply earlier :)

A Syllable definition, as apposed to just one for AtheOS is becoming more
and more important.  I see no reason not to include your patch.  I can't
say when I shall have a new release of Gcc ready, though.  I do not build
Gcc as part of the normal build process!

I notice that ALTOS and __ALTOS__ are also defined...should these be
removed?
I cannot think of anything that should still be using these (Ancient)
definitions, although some deeply buried kernel or libatheos code may be, I
guess.  A good grep is in order ;D

In addition, it some point we will change the output of uname -a to
"Syllable",
and not "AtheOS".  This will break existing configure scripts as they check
for
"AtheOS"; it will be a period of chaos until packages pick up the updated
config.guess and config.sub for Syllable.  However, it does give us an
advantage
that we can identify Syllable features easier.  I do not know when that will
happen exactly, but it will probably be at the same time as we switch to Gcc
3.x
(Probably the 0.5 release, maybe about 5 or 6 months from now)
