| 4 | Subject: [PATCH] src/internal: Use __GLIBC__ to check for GNU extention |
| 5 | implementation |
| 6 | |
| 7 | __USE_GNU is defined by _GNU_SOURCE and configure explicitly sets this |
| 8 | macro and it does have meaning on musl too, where it may have some level |
| 9 | of GNU compatibility but strerror_r is not one of them. Therefore we |
| 10 | have to check for libc implementation for this to be sure. |
| 11 | |
| 12 | Upstream-Status: Pending |
