Additional info:

As a QnD test I've added dummy stubs that return -1 (error) for these three methods to WebCore/platform/gtk/FileSystemGtk.cpp.  Doing that at least gets the build to complete w/o error.

A little investigation leads me to believe that:

1.) To implement 'PlatformFileHandle openFile(const String& path, FileOpenMode mode)' for the GTK platform, a wrapper for 'int g_open(const gchar *filename, int flags, int mode)' is needed.

2.) To implement 'int readFromFile(PlatformFileHandle handle, char* data, int length)' for the GTK platform, a wrapper for 'gboolean g_file_get_contents(const gchar *filename, gchar **contents, gsize *length, GError **error)' is needed.

3.) To implement 'long long seekFile(PlatformFileHandle handle, long long offset, FileSeekOrigin origin)' for the GTK platform, a wrapper for 'GIOStatus g_io_channel_seek_position(GIOChannel *channel, gint64 offset, GSeekType type, GError **error)' is needed.

I'm not a low-level GTK developer, having only done some simple GUI design/use, so I'd say I'm not the best person to implement these.  Any GTK developer out there, for whom this is a half-hour hack?  TIA!
