I looked through Bruce's pages before starting, and got some useful tips
from there, even though I took a slightly different approach.

At the moment, I'm too pushed for time to do justice to a FAQ, which would
really involve doing a lot more testing and investigation - my program was
very small (not quite just a button connected to a blinking LED, but not far
off it).  If this is successful and we do more with Tinys, then I'll have
more information to share.  Otherwise, if there is enough interest then I'll
see if I can write up a little more.

Looking forward, I think gcc 4.0 and 4.1 might be much better for the AVR
Tiny - as far as I understand it, the newer inter-procedural optomisations
could make a big difference to the code.
