    gio/ginetaddress.c: Fix Windows XP inet_pton() Emulation
    
    We need to be more careful when we try to assign values to gpointers, so
    that means we have to assign the value to the properly-dereference
    gpointer, so that the assigned value will be retained after the function
    returns.  This code will be dropped soon, but it is done for XP
    compatibility's sake for 2.44.
    
    Should fix the issue reported in bug 730352 comment #24.
