 *
 * NOTE 2: Many winsock structs such as servent, hostent, protoent, ...
 * are used with 1-byte alignment for Win16 programs and 4-byte alignment
 * for Win32 programs in winsock.h. winsock2.h uses forced 4-byte alignment.
 * So we have non-forced (just as MSDN) ws_XXXXent (winsock.h), 4-byte forced
 * ws_XXXXent32 (winsock2.h) and 1-byte forced ws_XXXXent16 (winsock16.h).
