[En-Nut-Discussion] unix emulation in ethernut-4.0.0

[Jose Vallet]

2 mistakes.
-Ethernut version that I am using is 4.4.0, not 4.0.0
-The list of undefined references were obviously taken from a different 
example that I tried to compile, not the "simple" one. But the details 
of the output are correct. Anyway the problem is the same.

I would appreciate any suggestion, but I will keep on trying! :-)
