o Conditionalize sections for POSIX.1-2001 compatibility.
o Use POSIX spelling for types, where possible. o Define size_t in the __BSD_VISIBLE case (this isn't really needed for standards conformance, but follows the tradition of not requiring <sys/types.h> as a prerequisite). o Use _BYTE_ORDER and friends instead of BYTE_ORDER and friends, since there may not be enough pollution in order for the latter to work. o Add an XXX note about the missing IPPROTO_IPV6 macro.
