| Subject: [PATCH] GNU version of strerror_r not available on musl |
| |
| The GNU version of glibc' `strerror_r` is non-portable. |
| |
| When the POSIX and GNU API collides musl always provides the POSIX API. That |
| being the case for `strerror_r` musl does only support the POSIX version, |
| despite of `_GNU_SOURCE`. |
