std and tr1 namespaces for Intel C++ and C++0X
I am interested in suggestions for std::tr1:: namespace alias's.  I use Intel C++ 11.0 on Windows.  The following are using Intel C++ within Visual Studio 2008.

1) I am currently using boost::function, etc. directly.  Should I be using one with the built in compiler?

I am able to: #include <array>
but when I look at the file, it appears to be coming out of the Visual Studio includes instead of intel?  Is this expected behavior or do I have something setup wrong?  What about when I compile with Intel C++ 11.0 on Linux?

2) I am using the std:c++0x when I compile and compile to keep up as C++0X features sneak in.  With C++0X, are the current tr1 features expected to be in the std:: or std::tr1:: namespace (or both?)?  Can I do a hack like the following temporarily until C++0X?:
namespace std {
using namespace ::std::tr1;
}

I know you aren't supposed to do this, but I would hate to force the ugly std::tr1:: throughout my code if it is dissapearing soon.

Intel does not provide its own C and C++ libraries with just a few exceptions for things like the
math library. When you #include a header file it will just pick up the same one you would have
gotten had you been using Microsoft on Windows or Gnu on Linux/Mac.

Most of the classes that were in technical report 1 have been accepted into the new C++0x standard.
I presume that the Gnu and Microsoft libraries at some point will put them into namespace std.

C++0x tr1 library relate to VC++ and  GCC library ,Only New C++0x language syntax relate to intel C++ compiler !
