[En-Nut-Discussion] Imagecraft and strtok_r in 4.6er release

Did'nt we always miss to fix those little things? :-)

Btw: If you plan the release a 4.6.1 version soon. I still have my ICMP
destination unreachable code in my desk drawer. I could add this code
for the next release, if you like. As it would change the behaviour of
NutUDPSend and NutUDPReceive it is deactivated by default and first
needs to be activated by a socket option.

Strange, but the crt files should be compiled for ICCAVR too, right?
Perhaps obj-dump (does imagecraft support similar tools?) could help to
figure out, if the symbol is available? Perhaps just a missing entry in
a makefile?

I suppose it will be, shure. Your code is just a specialized version of
mine. Question is if it's that much faster to outweigh a more general
solution.
