If I add this sort of junk to the top of my test scripts then they 
seem to pass the tests:

set -e
SRCDIR=`dirname $0`
SRCDIR=`cd $SRCDIR && pwd`
TOPSRCDIR=`cd $srcdir && pwd`
cd utilities || exit 1

MODEL_MIFF="${TOPSRCDIR}/Magick++/demo/model.miff"
.
.
.

Without the pwd's distcheck can't pass since srcdir may be passed as a 
useless '.'.

Unfortunately, with hundreds of such scripts, altering the test 
environment to convert to a non-recursive make is quite a penalty.

Many scripts could be one-liners if Automake can produce a 
per-directory test environment.
