2046 | * on scripts that have those now-otherwise-useless bits set. The setuid | |

2049 | * the same argv that it had. If suidperl finds that the script it has | |
2050 | * just opened is NOT setuid root, it sets the effective uid back to the | |
2051 | * uid. We don't just make perl setuid root because that loses the | |
2052 | * effective uid we had before invoking perl, if it was different from the | |
2053 | * uid. | |
