They could, but if it is unnecessary it is an unnecessary hassle.
(And it can be quite a pain getting autoconf flex and bison installed.)

But not configure, flex and bison.

True, bugt AFAIK the assumption is wrong.
The generated configure script and flex and bison code _should_
be platform independant. If it is not, the right way would be to fix
them.

Actually I think that this question mark helps clarify the situation
of the files. The actual behaviour of CVS is the same in this case.

True, because they are not there, if they do not belong in CVS: :)
