I recently updated to Ubuntu 13.10, where g++ 4.8 is the default
compiler. When trying to compile unit tests I got all sort of unused
typedef warnings, which was really annoying, and I had to install g++
4.7 to be able to avoid them. Hopefully what you propose will change this.
BTW, it would be convenient to explain in more detail what you mean by
"initialize the new module".
Thanks for taking care of this.
