[En-Nut-Discussion] Programs compiled under Linux do not work

[Harald Kipp]

Raphael,

Just stumbled over a similar problem.

One of this is an include file problem
(avr-libc) in conjunction with supporting two
different compilers and CPUs.

I attached an updated compiler.h.

Shame on me. I currently have installed some
old stuff, taken from

http://www.chaos-web.de/avr/

This is completely unofficial, experimental and
outdated, but works with ATmega103 and 128 on
Redhat 7.3.
