Windows sockets (select missing events?)

Hi,

The type of field fd_count is defined in winsock.h:
typedef unsigned int u_int;

So in the struct fd_set,
the field fd_count is unsigned int.

The pgwin32_select function has loops that use *int* as indices.

Question: in Windows, the socket select function isn't missing some events?

If not, It would be a good prevention practice, using the correct type,
right?

Patch attached.

best regards,
