Thanks for reporting. This is exactly the kind of stuff one is
expected to come across when porting GLib to Win64.

It can't be a SOCKET because we don't want to have to include
<winsock2.h>. It should be some other integer type that is 32 bits on
Win32 and 64 bits on Win64. Hopefully this can be handled without any
need for #ifdefs.
