C++ – Are there some better ways to address warnings when compiling protocol buffer generated source file

For a simple proto file:

message Person {
  required int32 id = 1;
  required string name = 2;
  optional string email = 3;
}

It's been compiled by protoc.exe and the results are used in an also simple test project, which basically does nothing but including the protoc generated files.

I'm using the msvc10 to build the test project (x64), then it gave me a lot of warning:

Is there any good way to address all of these warning? Any suggestions will be greatly appreciated.

ps. the libprotobuf project itself can be clean compiled by msvc10 without any warning.

working solution:

1. set properties for those protoc generated .cc files:
   
   configuration properties -> c/c++ -> advanced -> disable specific warnings
