--- Comment #1 from Eric Gallager <egallager at gcc dot gnu.org> ---
Confirmed, my (old) version of clang says:

$ /sw/opt/llvm-3.1/bin/clang++ -c -Wall -Wextra -pedantic 77618.cc
77618.cc:3:15: warning: explicit instantiation of 'foo<int>' that occurs after
an explicit specialization will be ignored (C++11 extension)
[-pedantic,-Wc++11-extensions]
template void foo<int>();
              ^
77618.cc:2:18: note: previous template specialization is here
template <> void foo<int>() {}
                 ^
1 warning generated.
