I certainly prefer this alternative (the use of extern for that purpose

if N is not equal to 2 or 4, one gets the following error
error: size of array 'l' is negative
Would not it be better to have an explicit test of N being 2 or 4, and an error
of the kind "the vector size has to be the size of 2 or 4 long" if not?
There's no way to tell the compiler to emit that kind of error (in C;
that's what C++11 static_assert is for).
