FD_ISSET replacement

[Simon Josefsson]

The sys_socket module generates this warning:

../lgl/sys/socket.h: In function 'rpl_fd_isset':
../lgl/sys/socket.h:158: warning: comparison between signed and unsigned
../lgl/sys/socket.h:159: warning: comparison between signed and unsigned

I pushed the patch below.

However, is the code really appropriate?  I'm thinking of this comment:

 /* Re-define FD_ISSET to avoid a WSA call while we are not using
    network sockets.  */

Given the winsock-select.c code, it seems that we may be using network
sockets?
