`make tests' (or `test' or `check') from the build directory runs the
bash test suite.  The first thing it displays is intended to explain the
output:

"Any output from any test, unless otherwise noted, indicates a possible
anomaly"

The only output should be the name of the test (e.g., run-exp) and any
warnings that test displays about the expected output, e.g.

"warning: the text of a system error message may vary between systems and
warning: produce diff output."

If you get diff output (lines prefixed by `<' or `>') and there isn't a
warning associated with the test telling you it's expected, that's a
problem.
