on Windows platform new functions use native Windows API. 
In particular _wsopen_s is called instead of g_open on Windows. 
g_open works on Windows, but we cannot close the returned handle properly.
The handle must be closed with close() function from GTK+ CRL, 
but we have no access to it. We only have _close() from MS CRL, 
it cannot close the handler returned from other CRL. 
When StarDict is build with Visual Studio we have two copies of CRL:
one from Microsoft and one from GTK+ runtime. */
