| 4 | Subject: [PATCH] Adding ability to detect non-posix extensions for pthreads |
| 5 | |
| 6 | Theres a desire to build rngd with musl, which doesn't have all the gnu |
| 7 | extensions (but it has some). So test for those. Note, this requires |
| 8 | the addition of the USE_EXTENSIONS macro to enable -d_GNU_SOURCE |
