The plus of this header is also that it'll work in R5 without having to
link against an extra object file. OTOH the OpenBeOS kernel has more of
these functionalities built in - so maybe we should think about making
some of them public API.
Exporting them as modules would have the advantage of being free to
change the internals without breaking any compatibility. It would keep
the kernel API at a minimum which is great for development it
further...
Adios...
Axel.
