Should I use __restrict on references?

In the program I am coding, one of my function declarations goes like this:

bool parse( const sentence & __restrict sentence )
{
  // whatever
}

When I compile the code with Microsoft Visual Studio 2010 Express, the compiler complains:

warning C4227: anachronism used : qualifiers on reference are ignored

However, this page of GCC’s documentation says:

In addition to allowing restricted pointers, you can specify restricted references, which indicate that the reference is not aliased in the local context.

And the same page gives a very explicit example:

 void fn (int *__restrict__ rptr, int &__restrict__ rref)
 {
   /* ... */
 }

Did I misunderstand MVSC’s warning? or should I transform all my references into pointers so that __restrict applies?
