------- Comment #3 from geoffk at gcc dot gnu dot org 2007-05-02 00:54 ------- You would add a translation unit that says
int i; or similar. It's not "main::i", it's "::i", because of [basic.link] paragraph 7: When a block scope declaration of an entity with linkage is not found to refer to some other declaration, then that entity is a member of the innermost enclosing namespace. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31775
