| 4 | Subject: [PATCH 1/2] configure: Remove obsoleted -malign-{jumps, loops, |
| 5 | functions} |

| 10 | The GCC warns "cc1: warning: ‘-malign-loops’ is obsolete, use ‘-falign-loops’". |
| 11 | The Clang silently ignores -malign-{jumps,loops,functions}. |
| 12 | |
| 13 | The preferred -falign-* forms have been supported since GCC 3.2. So, just |
| 14 | remove -malign-{jumps,loops,functions}. |
