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