Just noticed this bug myself.  You can work around it by creating
a temporary typedef.  E.g.,

  typedef typeof(obj) T;
  T::size_type s;

Still annoying though.

The error message is now:
tests/pr6709.cc: In function `int main()':
tests/pr6709.cc:10: error: `X' in namespace `::' does not name a type
which shows what is happening now.

This workaround is required for decltype, I don't see why typeof should be any
different.

The reason is that decltype(obj) doesn't declare a new type-name, it is only a
simple-type-specifier, which cannot appear in a nested-name-specifier.

The typedef workaround introduces a new type-name, which is allowed in a
nested-name-specifier.

In Bug 43285 Comment 1 I said that I think decltype is invalid in this context,
which would make this a documentation bug for C++.

In the C++0x grammar:

simple-type-specifier:
  ::_opt nested-name-specifier_opt type-name
  ...
  decltype ( expression )

nested-name-specifier:
  type-name ::
  namespace-name ::
  nested-name-specifier identifier ::
  nested-name-specifier template_opt simple-template-id ::

type-name:
  class-name
  enum-name
  typedef-name

So decltype(expression) cannot appear in a nested-name-specifier

Hmm, I wonder what the current draft of C++0x says of decltype with this
respect (right now we reject it).
