why?

As Alf said, float4 doesn't satisfy the vector templates' requirements
as a value type.
If your C++ implementation ships with the TR1 library extension or you
can install some TR1 implementation and/or Boost you could solve this
problem via:
typedef std::tr1::array<float,4> float4;

Apparently GCC considers this a bug (http://gcc.gnu.org/bugzilla/
show_bug.cgi?id=40192). So now I'm doubly confused.
I'm not a language lawyer, is "float4" a pointer to an array of 4
floats? Or is it an array of 4 floats? Basically if we define float4_t
as "struct float4_t { float x,y,z,w; };" is std::vector<float4>
equivalent to std::vector<float4_t> or std::vector<float4_t *>.
Thanks,
