You may hardly believe this, but IMHO the majority of Nut/OS
applications are running on 8-bit targets, where even 16 bit accesses
are not atomic.

Beside that, 64 bit values should be limited to environments, which are
well known to support this. The Nut/OS kernel should not depend on more
than basic C89.
