| 2 | Subject: [PATCH 05/12] ltmain.in: Don't encode RATHS which match default linker paths |
| 3 | |
| 4 | We don't want to add RPATHS which match default linker search paths, they're |
| 5 | a waste of space. This patch filters libtools list of paths to encoode and |
| 6 | removes the ones we don't need. |
| 7 | |
| 8 | Libtool may be passed link paths of the form "/usr/lib/../lib" so normalize |
| 9 | the paths before comparision. |
