naming protobuf field as "value" results in compilation error in XXXSpecified (valueSpecified) setter

[GoogleCodeExporter]

Compilation error:
Error   Type of conditional expression cannot be determined because there is no 
implicit conversion between 'bool' and 'string' 

    private string _value;
    [global::ProtoBuf.ProtoMember(3, IsRequired = false, Name=@"value", DataFormat = global::ProtoBuf.DataFormat.Default)]
    public string value
    {
      get { return _value?? ""; }
      set { _value = value; }
    }

[global::System.Xml.Serialization.XmlIgnore]
    [global::System.ComponentModel.Browsable(false)]
    public bool valueSpecified
    {
      get { return _value != null; }
->>>>>      set { if (value == (_value== null)) _value = value ? value : 
(string)null; }
    }

Suggested workarounds:
1. rename "value" property in proto file to something different (avoid using 
keywords).
2. When code of XXXSpecified is generated add "this." to reference every class 
member.
