--- Comment #13 from Thomas Koenig <tkoenig at gcc dot gnu.org> --- I am not sure what to do with this failing test case. To me, this sounds more like a problem with your test setup. execute_command_line calls the C system() function. What does that do on your system if there is no /bin/sh? Anything useful?
