| 4 | Subject: [PATCH] configure.ac: add library if header found |
| 5 | |
| 6 | If the pthread.h header is found, make sure library containing |
| 7 | "pthread_atfork" is added to the list of libraries against which to link. |
| 8 | On some hosts (e.g. openSUSE 15.1) "-lpthread" needs to be explicitly added |
| 9 | in order for the code to compile correctly. |
