Cool - thanks. Strangely the (correct) script that Chris linked to his
reply has a clang path in PREPENDPATHDIRS but I don't really know what
it does with it. It looks like, potentially, clang could just be added
as an alternative without any changes to the machine itself (if that
path, /opt/clang-releases/llvm/bin, is usable) though given llvm-gcc's
limited future it might as well be removed.

Thanks - I'd gotten the link (& started thinking about the demo page
to see if it had 0x support, etc) from a recent clang checkin. It
looks like it's a clang copy & there's this file:

It seems like that directory's a bit redundant & rather than having a
separate clang demo, we'd just update the llvm demo to use clang
instead of llvm-gcc, yes?

I'm wondering what would be the most practical way to work on
improvements. Small ones that don't require testing (if there's
already support for one command line argument, say, then adding more
shouldn't be painful/hard/risky) I can submit patches for & wait for
them to go live, but I wouldn't want to burden the list with lots of
patches as a means of developing/debugging/fixing changes when they go
live. I guess it would be easier for someone with direct access to the
machine to just hack at the script & check the changes live, then
checkin the result.

But I'm happy to have a crack at blind/unvalidated patches to improve
the functionality if that's useful.
