Improve configurability of testtagsguards.sh
There is a list of variables at the top of the file, but they are not configurable. Also, it is not possible to use a C++ compiler other than clang++.
I just realized on another PR that this does not work, but the error does not show up as a non-zero exit code from testtagsguards.sh. Does this syntax require a special shell? See my new comment on
PR merged. Ticket done?
