I've hacked that one about a bit, but here is another, and the exact
error message. 
I now have 3 lines.

1) Does an ls, which reports the file does not exist.
2) Tries unsuccesfully to copy the file.
3) 'atlc' tries unsuccesfully to use the copied file.
4) Tries unsucessfully to report computer by the program 'atlc'

#! /bin/sh
ls -l $top_srcdir/examples/undefined_permittivities.bmp
cp $top_srcdir/examples/test-coupler1.bmp $top_builddir/tmp
Zo=`$top_builddir/src/non_gui/atlc
$top_builddir/tmp/undefined_permittivities.bmp`
echo Zo = $Zo

The exact message generated are:
../../examples/undefined_permittivities.bmp: No such file or directory
cp: cannot access ../../examples/undefined_permittivities.bmp
cannot open ../tmp/undefined_permittivities.bmp


The messages suggest the files does not exits, but it does:

% find . -name undefined_permittivities.bmp
./examples/undefined_permittivities.bmp

So 'undefined_permittivities.bmp' does exist, but neither ls or cp can
find it when I do a 'make distcheck'. But when I do a simple 'make
check', both ls and cp file it okay and the test passes. 

As you see below, ls reports the file size, cp produces nothing to
stderr and the value of Zo gets printed and later checks produce a
pass from the test. 
-rw-r--r--   1 davek    staff     132330 Apr 17 14:49
../examples/undefined_permittivities.bmp
Zo = 24.86
PASS: 15a-undefined_permittivities.test


The top srcdir looks like this, with the example directly off the top
source directory. A file $top_builddir/tmp is created elsewhere. 
.
./examples
./tests
