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

[José Vallet]

Has anybody got it working?

I am able to get to the point where I get undefined references to 
`pthread_create', `pthread_sigmask', `NutGetTickClock', 
`NutTimerMillisToTicks' and `NutEventPostAsync' when I compile the 
simple example from the applications.

Find attached the details. Any suggestions?

Thanks!
José
