4 # tests below ignores it because it will vary a bit depending on endianness and
5 # floating point precision.  test-multipath will output an error message on
6 # stderr and return with exit code 1 if anything really goes wrong.  In each
7 # case, we list the (approximate) expected output in a comment to aid debugging
8 # if the test does fail.
