I'm trying to compile sharpssh which is a port of jsh : a library to connect to
SSH...

This library override the string object as java.String...

i've made a test case that shows up the problem :

using System;
using String=Tamir.SharpSsh.java.String;

namespace TestCompiler
{
        class MainClass
        {
                public static void Main(string[] args)
                {
                        Console.WriteLine("Hello World!");
                        String a="bonjour";
                        int i=1;
                        Console.WriteLine(i+a);
                }
        }
}

this compile with :
