Great! Thanks! I'm looking forward to your pull request or patch. If you want to go the patch route, please open a bug report.

Why do you want to compile test-core in C++? 

C++ unit tests should use Google Test, aka gtest. The master branch is already set up for it, you just need to enable it in configure and tell configure where the sources are, unless you've got a distro like Debian than installs them in /usr/src, in which case configure can find them on its own.
