[Ada] GNAT.Sockets: refactor Has_Sockaddr_Len
Use a field offset computation trick to avoid maintaining a list of
platforms.
2019-07-01 Dmitriy Anisimkov <anisimko@adacore.com>
gcc/ada/
* gsocket.h (Has_Sockaddr_Len): Use the offset of sin_family offset in
the sockaddr_in structure to determine the existence of length field
before the sin_family.
