I don't think we do know how large to make the vector before recording 
things in it. Each vector records the IDs of all the units that that can 
reach a particular tile in one (or two) turns. How can we know that 
before computing the movemap? If specvec provided a push_back function, 
as the std::vector template of C++  does, we could use a specvec.

Or am I missing something?

Note that the genlist are never used directly outside the movemap code 
itself; the provided movemap_iterate_one_turn and 
movemap_iterate_two_turn macros hide it.
