# calling Clang with all warnings, except:
# -Wno-documentation-unknown-command: code uses user-defined commands like @complexity
# -Wno-exit-time-destructors: warning in Catch code
# -Wno-keyword-macro: unit-tests use "#define private public"
# -Wno-deprecated-declarations: the library deprecated some functions
# -Wno-weak-vtables: exception class is defined inline, but has virtual method
# -Wno-range-loop-analysis: iterator_wrapper tests "for(const auto i...)"
# -Wno-float-equal: not all comparisons in the tests can be replaced by Approx
# -Wno-switch-enum -Wno-covered-switch-default: pedantic/contradicting warnings about switches
# -Wno-padded: padding is nothing to warn about
