Sorry, Uwe, either I missed or forgot it.

The problem is related to avr-libc. Since version 1.8 several data types
had been removed, including the often used prog_char. I'm able to
compile for avr-libc < 1.8 or avr-libc >= 1.8, but I never managed to
get the same code linked with both versions.

If possible, I'd like to support both to keep Nut/OS upgrades
attractive. Users may boggle, if they are forced to switch the toolchain
too, because that may require large changes in their existing code too.

Thanks for your offer.
