Ok, I have a system at work that is using custom methods, both TCP and UDP,=
 and multicast / unicast. Now, I am getting stumped with the GNAT.Sockets t=
ranslation of the equivalent connections, probably because I've not used So=
ckets before and most of the examples I've tried haven't worked.

Most of the messages can, I think, be mapped out to Ada's records fairly ea=
sily but that's getting ahead of myself =E2=80=94 what I'm having trouble w=
ith is getting a socket to receive from the proper multicast address[es] =
=E2=80=94 there is a note in the GNAT.Sockets example [which isn't working]=
 that joining a multicast-group has to be set as an option subsequent to bi=
nding the socket when running on Windows.

(Is there a better package/library for operating on sockets? I've done a li=
ttle searching, but I haven't found anything that looks particularly good.)
