+Summary: delegates to call cdecl native code
+
+Please fill in this template when reporting a bug, unless you know what 
+you are doing.
+Description of Problem:
+
+Mono doesn't do delegates with the attribute to specify that if they're  
+used to call native code, said code uses the C (cdecl) calling convention, 
+rather than the Pascal (stdcall) calling convention that's the default for 
+Microsoft C#. The syntax goes thus:
+
+    [UnmanagedFunctionPointerAttribute( CallingConvention.Cdecl)]
+    public delegate int TEST_callback_f_t(int a, int b);
+
+Steps to reproduce the problem:
+1. Try to compile code with that attribute. 
+2. 
+3. 
+
+Actual Results:
+
+Compile failure, I presume - I was asked to submit this bug when I asked 
+if Mono could do this. 
+
+Expected Results:
+
+
+How often does this happen? 
+
