I 'think' it is this:

-> G++ now correctly implements the two-phase lookup rules such that an
unqualified name used in a template must have:

(1) an appropriate declaration found either in scope at the point of definition
of the template; or

(2) by argument-dependent lookup at the point of instantiation.

The question is if you have (1) & (2) instead of (1) | (2) do you get this
redeclaration error??
