 * socketcompat.h: Socket compatibility for Windows, making it slightly
 * less painful to use.
 *
 * Use this header under the following circumstances:
 * (a) Instead of including any of: <net/if.h>, <netinet/in.h>,
 *     <sys/socket.h>, <netdb.h>, <netinet/tcp.h>, AND
 * (b) The file will be part of what is built on Windows (basically
 *     just remote client stuff).
 *
 * You need to use socket_errno() instead of errno to get socket
 * errors.
