+The program that doesn't work (probably because of bugs in the
+marshaling code) is this:
+using System;
+using System.Runtime.InteropServices;
+
+class GSL
+{
+        [DllImport("libgsl")]
+        static extern complex gsl_complex_sin (complex z);
+
+        public struct complex
+        {
+                [MarshalAs(UnmanagedType.ByValArray, SizeConst=2)]
+                public double[] dat;
+
+                public complex(double re, double im)
+                {
+                        this.dat=new double[] {re,im};
+                }
+        }
+
+        public static void Main()
+        {
+                complex c1 = new complex (3, 4);;
+                complex c2;
+                c2=gsl_complex_sin(c1);
+
+                Console.WriteLine(c1.dat[0]);
+                Console.WriteLine(c2.dat[0]);
+        }
+}
