Thank you all for all the really helpful replies, much
appreciated.
You have certainly put my main fear at bay (that I
might have to recode whole chunks), and I'm very
grateful to those who said they would be happy to
check out my app on their own Intel systems - many
thanks.
I've taken your advice and made sure my project is set
to use gcc 4.0, and I guess I'll just forge ahead and
deal with any issues that arise when the first Intel
machines come into the shops. I'm thinking that maybe
once the app's complete, I might just keep it in
public beta for an extended period until I get chance
to test it on an Intel machine myself.
Thanks again,
Keith
