After noticing that there are still some people who retrieve the
fairly old version of my demo program, i've made an update available.
It's now packed into a .zip file, and the schematics is already in PDF
format to help out the Windows users who usually have problems viewing
a PS file.

You can find it at ftp://ftp.ifbus.de/pub/j_wunsch/avr-demo.zip

The demo was originally intented to accompany Rich Neswold's avr-libc
documentation, but then, well, developed to something that
demonstrates almost any of the underlying concepts of avr-gcc.  It's
still just a simple PWM-driven LED (like Rich originally intented),
but there are options to control the LED via RS-232, or via an analog
input (when using an AVR that has an ADC, of course).

The updates mainly consists of small bugfixes, for things where gcc 3
is pickier than 2.x used to be.  Also, the detailed code size analysis
at the top of the program has been updated -- gcc 3 generated about 10
% smaller code than 2.x did.  Unfortunately, using the itoa()
conversion from libc eats up the difference, but my old hand-crafted
version turned out to be buggy anyway.  But i hope the size analysis
give people a hint about how to interpret the output of avr-size and
