[gtk+/gtk-style-context] Work harder at parsing import statements

[Matthias Clasen <matthiasc src gnome org>]

commit 85fc6e8c3dfe7d79f5c8bcaa84f93beedef652a9
Author: Matthias Clasen <mclasen redhat com>
Date:   Thu Nov 18 01:59:27 2010 -0500

    Work harder at parsing import statements
    
    Also, turn g_warning() into g_message() for now, so that tests
    don't abort. Eventually, this needs to all go into GErrors.
