I consider the new way better as it is easier to detect this kind of |
| 21 |
problems that way. |

Thank you very much for your help. |
| 42 |
I took a quick look in the ddd configure script and it indeed links |
| 43 |
against libelf if it is available, without a possibility to |
| 44 |
explicitely turn it on or off by a configure flag. |
| 45 |
I have assigned the bug accordingly. |
