--- Comment #31 from Tamar Christina <tnfchris at gcc dot gnu.org> --- > It seems that some paths are properly translated though, for example the > library paths. Do you know why? It would be nice to have the gnatlink > command line that gave rise to the invocation quoted in the dump screen.

The unquoted ones are fine.
