Removing private class members, code unused by ETL in "private"
namespaces, code unreachable via preprocessor guards (C++11 inside

tests.
* Print test names at test time (#1343)
* Suppress false positive compiler warnings when compiling with -O3
The CI checks currently only check everything with -O0. Wenn activating
higher optimization levels, more warnings kick in. Leading to errors,
depending on the configuration.
