Ulf, while we have you "on the line," let me ask another thing...
Over the weekend I tried out both ImageCraft C and GCC. (With a small program I got very similar results; I didn't try anything big enough to really bring out a difference.)
What impressed me is that AVR Studio comes preconfigured for GCC, and once I installed WinAVR (even though I didn't install it in the usual place), AVR Studio found it and used it.
Is Atmel making a long-term commitment to GCC? Is the library going to grow? I imagine having all the functionality of BASCOM (hardware and software UARTs, LCD interfacing, etc.) available in GCC.
Thanks, Michael
