Dear Michel,

Thank you very much for your message. At some point I changed
something in the implementation and had to reorder the steps in the
detail namespace. I did not see that the definition of the detail
operator was coming too late but nothing told me the contrary because
there was no failure with g++ and intel-linux. Now that you say it, I
wonder why it works for other compilers!

I have applied the changes and all tests still pass with g++ 4.5.2 and
4.6.1 and intel-linux 11 and 12. So I believe it is safe.
Committed to trunk r74924. Can you rerun the test on the trunk? I will
then ask for permission to merge to release if everything is fine (I
would also wait for new testing with msvc).

Frédéric
