GtkSharp/generator/Signature.cs
Martin Willemoes Hansen c2d4c12e67 * generator/Method.cs: Methods which returns void and has a single out parameter
like void Foobar (..., out int baz, ...) are turned into the more .NET like
          signature int Foobar (...), this fixes bug 46392
        * generator/Signature.cs: Ditto
