I fixed up my delta script as I now finaly understood what it did:

#! /bin/sh
cp input.f90 /home/staff/paul/noo/src
make -C /home/staff/paul/noo DEBUG=1 lib
cp /home/staff/paul/noo/include/*.mod ./
cp /home/staff/paul/noo/testsuite/bugs/delta/gugv_ass_test_noo.f90 ./
mpif90 -c gugv_ass_test_noo.f90 2>&1 | grep -q fixup
if ! test $? = 0; then
        exit 1
fi
exit 0

The point is that the problematic file (matlib.f90) has to be compiled in the
original source directory using the original Makefile, because the error cannot
be reproduced reliably. Then the generated modules are moved to the current
directory and the problematic test case is compiled.

Now delta proceeds to remove ALL lines of code, so something is still wrong.
What are temporary source files in delta iterations called? (This is the file I
have to cp to src/matlib.f90.)
