Sigh... it turns out that gcc does not implement N3276 completely.
I just tested `boost_no_decltype_n3276.ipp`, but it failed to compile.

(I had tested decltype for incomplete return types that does not
involve any templates:

  struct S;
  S f();
  decltype(f())* ptr = 0;

This test ran successfully.)

I'll reopen the PR on gcc bugzilla.
