+
+Fix compilation error for pthread tid wrong init.
+
+poller.c: In function 'poller_map_add':
+poller.c:54:18: error: initialization of 'pthread_t' {aka 'struct __pthread *'} from 'int' makes pointer from integer without a cast [-Wint-conversion]
+   54 |
+      |
+
+Setting to -1 is wrong and actually not useful as it gets set right
+after if map is not NULL.
