GNU testsuite comparison:

GNU test failed: tests/misc/io-errors. tests/misc/io-errors is passing on 'main'. Maybe you have to rebase?
Skipping an intermittent issue tests/date/resolution (passes in this run but fails in the 'main' branch)
Skipping an intermittent issue tests/pr/bounded-memory (passes in this run but fails in the 'main' branch)
Note: The gnu test tests/cp/link-heap is now being skipped but was previously passing.
Note: The gnu test tests/printf/printf-surprise is now being skipped but was previously passing.

In future, could you minimise the diff by avoiding making unnecessary changes to type qualification.

These changes make error messages more consistent with GNU coreutils.

[oech3]

GNU's test suite stated extracting OS provided err messages and use it. So many tests might fail in the future by (os error N).
