      To test the results, issue: <command>LC_ALL=C ninja test</command>. One
      test, <filename>style / style-format</filename>, is known to fail due to
      differences between LLVM-16 and LLVM-17's version of clang-format.

      -->
      One test named <filename>libgweather / metar</filename> is known to
      fail because it requires some online resources which have been moved
