* system version of getXXXbyYYY is thread safe, the provided auxiliary
* buffer argument is unused and ignored.
*
* Target specific versions of GNAT.Sockets.Thin for platforms that can't
* fulfill these requirements must provide their own protection mechanism
* in Safe_GetXXXbyYYY, and if they require GNAT.Sockets to provide a buffer
* to this effect, then we need to set Need_Netdb_Buffer here (case of
