--- Comment #2 from Paul O'Neil <redballoon36 at gmail.com> ---
Per Martin's comments
(https://github.com/D-Programming-Language/druntime/pull/1034), this is a
compiler bug, not a problem with the code as originally written in druntime.

private inout(cmsghdr)* __cmsg_nxthdr(inout(msghdr)*, inout(cmsghdr)*) pure
nothrow @nogc;
alias __cmsg_nxthdr CMSG_NXTHDR;

CMSG_NXTHDR should have default protection instead of private.

In the meantime, PR 1034 has been merged; it uses a one-line function for
CMSG_NXTHDR instead of an alias.
