Namespace + STL internal error

[Chris Johns <ccj at acm dot org>]

hi,

Playing with namespace and STL I made the namespace the same as a stl
`set' object in a class. The attached file shows the error in about as
small a file I can. To see no error remove the SHOW_ERROR define.

I checked the known bug list and could not see it.

I am not on this bugs list.

Regards
