Well, by "port" I mean fixing problems like the ones below ...
There should not be much dietlibc specific stuff, but constants like
O_RDONLY make trouble sometimes as they should be the same everywhere
(clients and servers) and oskit has an own idea about this sometimes ...

Please do not expect to much here as this is currently no main project here.

Basically you should check all the libs in l4vfs and libc_backends_l4vfs.

Looks like you mixed oskit and dietlibc headers, probably not such a
good idea.  Stick to one libc or "know what you are doing".
