Comment (by cypherpunks):

 Replying to [comment:21 yawning]:

 I assume out_len just needs an explicit cast to int.  If the compiler were
 smarter it would see that, it's impossible for out_len to be big enough to
 where this warning has an impact, but so it goes.

 I'm thinking it's about the return value of `syscall`. According to the
 manual `syscall` returns a `long` but it's assigned to an `int`.
