Yup, I hope to have some more time next week and get it working for
ia64 also (or at least push it forward a bit).

I already sent you congratulations...

I just wanted to ask you about electronic version of your PhD. I am
sure it'll be very interesting reading.
I hope now you will be able to be a remove items from the TODO list
one by one? :-)   (by solving them of course)

BTW: When does UQAM finish the term? And when are the exams?
Right after new year I'd suspect? (I expect you to be busy at that time)

Look at that:
http://lists.debian.org/debian-arm/2001/debian-arm-200102/msg00157.html

<quoted piece>
This fails on a modern GCC, as 'arm' and '__arm' defines aren't set.
Adding '|| defined(__arm__)' in the correct place fixes things.
</quoted piece>

Wonder what's your compiler? However it can be that 2.95 uses
__arm and __i386 as for ex. in ./src/libsablevm/system.h:67 there is:

#if defined (__i386)

But if the above quote is correct, then we should change it to __i386__
We should do that at least because Debian and other distros will/already
have switch(ed) to gcc 3.X branch as the basic compiler.
BTW: Have you tried gcc 3.X Etienne? I am a bit worried that it can
break inline threading engine on every arch (only i386 currently).
A thing to be checked.

That's all for now, cheers...
