 This is from Paolo:
 
 Compile any test with a p/invoke method and disassemble the output:
 you'll note that, the parameter info table is not filled, so you don't
 get the name of the arguments, for example. The problem with marshaling

    The bug should be fixed on CVS.  Do you have a sample proggy that I
 can use to verify that the things are labeled as you want them?
 
    And what is MarshalAs support in MCS?

+You may try mono/tests/pinvoke.cs: in the ildasm output you'll note
+that the parameter names are there, while before this change they were
+not output.
+MarshalAs is an attribute that you can set to method parameters and to
+fields: it specifies what system type should be used when marshaling
+the parameter. Supposedly there is a Marshal Specification somewhere
+in the docs. There is some info in the docs for
+System.Runtime.InteropServices.MarshalAsAttribute.
+The compiler needs to support it since it's a special attribute (on
+parameters, for exampl, you need to set the info with
+ParameterBuilder.SetMarshal, I think).
