I’m not sure it has ever worked.
As a consequence, remove the workaround that had apparently been implemented in
tests/initval_file/ramst_initval_file.mod.
This directory is cluttered with so many files that it creates problem (e.g.
dynare-command-options/ramst.mod was broken under Octave because of this).
Move files that have to be found through the path in a utils/ subdirectory.
