I'm curious why you didn't use inheritance here.

     template<typename T>
     struct GTY(()) vec_t : public vec_prefix
     {
     ...
     };

Minimalism.  I was almost obsessed by it with the first patch.  It 
would've required more changes if I didn't make it a POD type.

I will make it into a more standard C++ type in subsequent patches.
