8 * NOTE: If you make any changes to fix a particular app, make sure
9 * they don't break something else like Netscape or telnet and ftp
10 * clients and servers (www.winsite.com got a lot of those).
11 *
12 * NOTE 2: Many winsock structs such as servent, hostent, protoent, ...
13 * are used with 1-byte alignment for Win16 programs and 4-byte alignment
14 * for Win32 programs in winsock.h. winsock2.h uses forced 4-byte alignment.
15 * So we have non-forced (just as MSDN) ws_XXXXent (winsock.h), 4-byte forced
16 * ws_XXXXent32 (winsock2.h) and 1-byte forced ws_XXXXent16 (winsock16.h).
