But the log you published says 4.0.1, that's why I am referring to 
4.0.1.  Nut/OS 4.0.1 definitely does not support avr-libc 1.4.2. I am 
not sure if 4.0.2 already has the updated gcc.h file and I did not say 
that 4.0.2 has the support. I only said, you need a more recent version.

Check the file nut/include/arch/avr/gcc.h which is causing the compiler 
warnings. This file must be Revision 1.2 or higher.

Alternatively you can switch off the compiler option to treat warnings 
as errors OR patch your gcc.h file as follows:

#if __AVR_LIBC_VERSION__ < 10400UL
#include <avr/signal.h>
#endif

Or use avr-lib 1.2.5.
