ok, no surprises there.

That's what I thought would happen since you don't have avr-libc installed
yet. ;-)

:)
:) Note:
:) avr-gcc -g -Wall -O2 -mmcu=at90s2313 -I../../../include   -c -o demo.o

:) WORKS :-/

Eek! So running those command in doc/example/demo work, but the standard
make doesn't.

One more thing I'd like to see. Do this (from top of avr-libc tree):

  $ make -C doc/examples/demo clean
  $ make -C build/doc/api demo

That looks fine to me. I assume that you used "--prefix=/src/install/" for
binutils and avr-libc also?
