Are you saying that the test itself should not make a decision as to
whether to exit with exit-code 77 (SKIP), or exit codes 0 and 1 ? i.e.
is the following fundamentally wrong for a test ?

# is this test not the way to do it ????
if [ 'some_condition is true' ] ; then
  MD5SUM=`$top_builddir/tools/src/mymd5sum $top_builddir/tmp/foo.bmp`
  if [ $MD5SUM = 847f4207b1b3cb708814ad9eff4736dc ]; then
    exit 0 # pass, right checksum
  else
    exit 1 # fail, wrong checksum
  fi
else
  exit 77  # skip this test
fi

In what file ? Does this include the two sets of quotes at each end -
I guess not?

That page don't work for me. Perhaps it's Internet Explorer specific,
but it fails to do anything sensible with my Netscape 4.78

I'm not quite sure what you mean here?
