C++ example does not make from scratch

Re: bison-2.3, fresh download from gnu.org mirror.

The example calc++ obscures the procedure for making it because the
distribution includes and uses the bison and flex outputs rather than
generating them from the input files.

I checked this by doing ./configure, make, and make in examples/calc++,
all under script(1), and the resulting typescript contained no, zero, nada
occurrences of invoking bison or flex.

It would be much more helpful if it built from scratch, so that us normal
users could see the commands that are used to make it on our configuration.
As it is, I had to guess (often wrong) about what was the original input
and what was generated.

I'm gonna guess you just have to put a few more things in your 'make clean'
so that the derivative files are not distributed.
