as much as possible: * dtable.cc: Drop including sys/socket.h. * fhandler_procnet.cc: Change includes accordingly. * fhandler_socket.cc: Ditto. (fhandler_socket::listen): Avoid gcc error message initializing sin6. (LPFN_WSARECVMSG): Only define when building against w32api headers. * net.cc: Change includes accordingly. Define USE_SYS_TYPES_FD_SET and __WSA_ERR_MACROS_DEFINED. Define _INC_NETIOAPI temporarily and explain why. (struct _IP_ADAPTER_UNICAST_ADDRESS_LH): Only define when building against w32api headers. (struct _IP_ADAPTER_ADDRESSES_LH): Ditto. (SIO_GET_INTERFACE_LIST): Ditto. (ws_freeaddrinfo): Rename from freeaddrinfo so as not to collide with Winsock declaration. Change througout. (ws_getaddrinfo): Ditto. (ws_getnameinfo): Ditto. * select.cc: Include netdb.h after defining USE_SYS_TYPES_FD_SET. * syslog.cc: Drop including netinet/in.h. Define USE_SYS_TYPES_FD_SET and include ws2tcpip.h. * include/netdb.h (struct addrinfo): Don't define when building Cygwin. * include/cygwin/if.h: Don't declare if_xxx functions when building Cygwin. * include/cygwin/in.h: Disable most definitions when building Cygwin. * include/cygwin/socket.h: Disable sockaddr and sockaddr_storage definitions when building Cygwin. Same for MCAST_INCLUDE/MCAST_EXCLUDE. * libc/inet_addr.c: Don't define __INSIDE_CYGWIN__ nor __INSIDE_CYGWIN_NET__. * libc/inet_network.c: Ditto. * libc/minires.h: Drop redundant inclusion of netdb.h. Define __INSIDE_CYGWIN_NET__ only before including netdb.h and resolver headers.
