Thanks for pointing this out. I've seen various suggestions that gcc-4.3.x is
needed for AVR, but nothing explicit why - until now.

Pity. 

I had just confirmed that (with minor changes to the Makefile) Warren's tutorial
works on the  Arduino Duemilanove.

Now it looks as if I need to find a native gcc-4.3.x for my system and start
again.
