No, I cannot. I should not have spoken before looking at the standard,
  sorry.

# 14.6.4 Dependent name resolution
# In resolving dependent names, names from the following sources are
#   considered:
#
# - Declaratinos that are visible at the point of definition of the
#   template.
#
# - Declarations from namespaces associated with the types of the function
#   arguments both from the instantiation context (14.6.4.1) and from the
#   definition context.

Seems to support your position as well. At the very least it seems 
  relevant.

I looked at 14.6.4.2, but bar<T> looks like a template id to me, so it
  didn't seem relevant.

I tried to find a general rule that 

Note that gcc will also reject a template dependent function call, if the
  function is not declared before the template definition. If you are
  correct (and now I think you are), this is also a bug, or an aspect of
  the same bug.
