I've attached 3 new diff files that include fixes for issues raised
by Andreas.  I plan to commit these patches tomorrow night (PDT) if
no one raises additional issues.  The patches have been regression
tested on i386-*-freebsd and amd64-*-freebsd.

If you want to regression test the patches, you CANNOT use 'svn switch'
to the fortran-experiments branch.  It is a long sordid story, filled
with deceit and ugly betrayal.  To test, you need to apply the diffs 
to trunk by doing

cd gcc/fortran
patch < ~/icb_fortran_2.diff
cd ../../libgfortran
patch < ~/icb_libgfortran_2.diff
cd ../gcc/testsuite/gfortran.dg
patch < ~/icb_test_2.diff

After testing, 

svn revert -R gcc/fortran
svn revert -R gcc/testsuite/gfortran.dg
svn revert -R libgfortran
svn status gcc/fortran | awk '{print $2}' | rm
svn status gcc/testsuite/gfortran.dg | awk '{print $2}' | rm
svn status libgfortran | awk '{print $2}' | rm
find . -name \*.orig | xargs rm
