    Silence compiler warnings for g_object_newv()
    
    GLib 2.53 has deprecated g_object_newv() and GParameter in favour of a
    more idiomatic g_object_new_with_properties() function taking an array
    of propert names and an array of property values.
    
    Since GJS is now in development, the default compiler flags include
    -Werror=deprecated-declaration, which breaks the build under the GNOME
    Continuous build.
    
    Silencing the compiler warning is the simplest way to avoid a build
    break.
