2 * based on Windows Sockets 1.1 specs
3 * (ftp.microsoft.com:/Advsys/winsock/spec11/WINSOCK.TXT)
4 *
5 * (C) 1993,1994,1996,1997 John Brezak, Erik Bos, Alex Korobka.
6 *
7 * NOTE: If you make any changes to fix a particular app, make sure
8 * they don't break something else like Netscape or telnet and ftp
9 * clients and servers (www.winsite.com got a lot of those).
10 *
11 * NOTE 2: Many winsock structs such as servent, hostent, protoent, ...
12 * are used with 1-byte alignment for Win16 programs and 4-byte alignment
13 * for Win32 programs in winsock.h. winsock2.h uses forced 4-byte alignment.
14 * So we have non-forced (just as MSDN) ws_XXXXent (winsock.h), 4-byte forced
15 * ws_XXXXent32 (winsock2.h) and 1-byte forced ws_XXXXent16 (winsock16.h).
