+Summary: mcs doesn't warn about [Obsolete] properties from other assemblies
+
+If you refer to an obsolete property in your own assembly, mcs gives
+a warning. But if you refer to an obsolete property in another assembly
+(eg, gtk-sharp.dll), it doesn't.
+
+danw@twelve-monkeys:tmp> cat oblib.cs
+public class Foo {
+        [Obsolete]
+        public int Bar { get { return 0; } }
+ 
+        [Obsolete]
+        public void DoSomething () { ; }
+}
+danw@twelve-monkeys:tmp> mcs -target:library -o oblib.dll oblib.cs
+danw@twelve-monkeys:tmp> cat obtest.cs
+public class Bar {
+        public static int Main ()
+        {
+                Foo foo = new Foo ();
+                foo.DoSomething ();
+                return foo.Bar;
+        }
+}
+danw@twelve-monkeys:tmp> mcs -r:oblib.dll -o obtest.exe obtest.cs
+obtest.cs(7) warning CS0612: 'Foo.DoSomething()' is obsolete
+Compilation succeeded - 1 warning(s)
+danw@twelve-monkeys:tmp>
+
+
+Note that it warns about the obsolete method, but not about the
+obsolete property. But if you merge the two into one file, it warns
+about both:
+
+danw@twelve-monkeys:tmp> cat oblib.cs obtest.cs > obtest2.cs
+danw@twelve-monkeys:tmp> mcs -o obtest2.exe obtest2.cs
+obtest2.cs(14) warning CS0612: 'Foo.DoSomething()' is obsolete
+obtest2.cs(15) warning CS0612: 'Foo.Bar' is obsolete
+Compilation succeeded - 2 warning(s)
