 The issue is that an `extern' implementation, unlike in C, requires
 some sort of hint as to what the impl is. An example is the DllImport
 attribute. If no such specification is given, it is a compile time error.
 There is probably a spec quote i could give...but dont know where i
 would find it.

+C:\Inetpub\ftproot>csc tt.cs
+tt.cs(2,21): warning CS0626: Method, operator, or accessor
+        'Test.does_not_work()' is marked external and has no
+attributes on it.
+        Consider adding a DllImport attribute to specify the external
+        implementation
+Unhandled Exception: System.TypeLoadException: Could not load type
+Test from assembly tt, Version=, Culture=neutral,
+PublicKeyToken=null because the method does_not_work has no RVA.
+So, it is actually an mcs warning, and mono should really throw a
+typeloadexception. I know we dont throw most of the loading
+exceptions, but for something like this,i would at least expect a nice
+error message.
