           Summary: gmcs doesn't special case Nullable<> constraints
           Product: Mono: Compilers
           Version: SVN
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Minor
          Priority: P5 - None
         Component: C#
        AssignedTo: mono-bugs at lists.ximian.com
        ReportedBy: rkumpera at novell.com

Under MS, Nullable<> is declared as: "Nullable<T> where T: struct, new()".

This construct is not allowed for regular C# code, but it happens to work for
Nullable.

This property might be verified by running the following program under MS and
mono:

using System;
class Driver
{
        public static void Main ()
        {
                Console.WriteLine (typeof
(Nullable<>).GetGenericArguments()[0].GenericParameterAttributes);
        }
}


MS reports: 
NotNullableValueTypeConstraint, DefaultConstructorConstraint

Mono reports:
NotNullableValueTypeConstraint


This is not a SRE issue as the API allows for such constraints to be defined.
