Oh promised lands of small happy libcs :-)
Back to the original problem - the i386 <asm/unistd.h> __syscall_return
macro which is used by the _syscallX macros set the errno variable - even
inside the kernel. In the age of SMP this looks broken - at least nothing
seems to rely on it. So how about removing the whole errno thing from
there?
