Interesting:

    % (cd build ; ctest --verbose -R test_m4)
    [...]
    
    3: Test command: /home/monnier/src/ctwm/trunk/build/tests/test_m4/test_m4 "-f" "/home/monnier/src/ctwm/trunk/tests/test_m4/ctwmrc"
    3: Environment variables: 
    3:  DISPLAY=
    3: Test timeout computed to be: 1500
    3: /usr/bin/m4: syscmd subprocess: No child processes
    3: /usr/bin/m4:/tmp/monnier/ctwmrc.XXAiGjku:31: cannot run command `/bin/rm /tmp/monnier/ctwmrc.XXAiGjku': No child processes
    3: OK

So the test encounters the same problem yet it passes.

Then again, maybe it's not that interesting since AFAICT it actually
runs the ctwm code, so it's no wonder that it behaves the same.

BTW, an interesting detail: there's no /tmp/monnier/ctwmrc.* file left
over, despite that message!
