[maemo-developers] [maemo-developers] automatic byte order check

The (linux) kernel has endianess-aware integer types (__be_u16 or
something similar) which allow the access to be checked for endianess
problems (basically reading an endianess-annotated type into a
non-endianess-specified (ie native endianess) type must go through a
byte order macro).

You have to annotate by hand all shared structures with these types.
In your case, this would be all network-shared structures.

I'm not sure the compiler does the check though, it may be an external
tool. It could be however very interesting to generalize this outside
of the kernel.
