well, there still can be some workaround:

adding a xcb_win32_init() function. This is an API addition, which makes 
the write of XCB-based progs consistent with the XCB API

Or we can add 1 member for the xcb_connection_t structure (which is 
available on Windows only, so no ABI break on non-windows platform)

  unsigned char wsa_is_init; /* set to 1 is wsa is alread init */

we init WSA on the connection creation if not alread init. And when we 
close the connection, we call WSACleanup() is init.
