My own. Those definitions are part of the kernel syscall. While glibc
does support structure definitions for most syscalls,
capabilities seem to be an exception. (they are in linux/capabilities.h
to be exact). Oh, and I really dislike the interfaces libcap provides.

I pull those definitions in myself now, because pulling in kernel header
files is considered a bad practice (c) Linus Torvalds
Since these won't add a byte of code, it might be a good idea.
I'm open for suggestions however.
