Both test failures have similar symptoms of failures due to spurious
CRLF differences, so let's look at the first failure.  Please run
this:

cd tests
./testsuite -v -d 22

and look at the file testsuite.dir/022/sets.  Does this file use the
CRLF convention of Windows, or the LF convention of Unix?

I'm asking, because ./testsuite uses the equivalent of the following
shell command to check testsuite.dir/022/sets, and I suspect there's
some problem with CRLF in this test.  Also, can you please try copying
the following shell command to a shell file, using LF only (since
that's what ./testsuite does, right?), and then executing that shell
file?  This will confirm my guess that it's a CRLF problem.

" | diff -u - testsuite.dir/022/sets


diff should read stdin and testsuite.dir/022/sets in text mode, so it
should ignore any trailing CR and the above command shouldn't output
anything; perhaps there's a problem with diff on your host?
