message:
  Don't make W32 code conditional on HAVE_SOCKETS, it's always defined.
  * w32.c: Remove top-level uses of #ifdef HAVE_SOCKETS.
    (gethostname) [!HAVE_SOCKETS]: Remove.
    (SOCK_REPLACE_HANDLE): Remove macro.
    (socket_to_fd, sys_close, _sys_read_ahead, sys_read, sys_write)
    (term_ntproc, init_ntproc): Don't conditionalize on HAVE_SOCKETS.
  * w32proc.c: Remove top-level uses of #ifdef HAVE_SOCKETS.
    (syms_of_ntproc): Don't conditionalize on HAVE_SOCKETS.
