Unfortunately, it looks like even the very limited functionality of aligned vs
template (see, e.g., c++/17743) is broken and I cannot even attempt implementing
tr1::type_traits::aligned_storage: the attribute seems completely ignored,
otherwise I could at least provide specializations for Align = 1,2,4,8,16...

Needless to say, Icc seems ok :(

Testcase (but, in case please test partial specializations too!):

//////////////

struct A
{ typedef char type[4] __attribute__((aligned(4))); };

template<unsigned _Len>
  struct B
  { typedef char type[_Len] __attribute__((aligned(4))); };

template<bool> struct StaticAssert;
template<> struct StaticAssert<true> {};

StaticAssert<__alignof__(A::type) == __alignof__(B<4>::type)> a1;
StaticAssert<__alignof__(B<4>::type) == 4> a2;

/////////////////

Giovanni can you please have a look?!? Thanks!
