Re: A new module: bitset

On the other hand, the module does not implement matrix operations
(matrix multiplication, transposition, determinant), only transitive
closure (which maybe is not so suitable for gnulib and should stay in
Bison?).

The definition 'typedef bitset * bitsetv;' is really an array of bitsets.

Good idea. Yes, 'vector' commonly means an array of variable size
(as in C++, Common Lisp, Java, ...).

This also means that bitsetv.h should probably be renamed to
bitset-array.h, not bitset-vector.h.

I agree.

The name conflict between bitset-vector.h and bitset/vector.h is superficial;
given that only the implementor knows about the second one, I find it
acceptable.
