With newer compilers the pid_max test is failing to build with the following build error: ... pid_max.c: In function ‘pid_max_cb’: pid_max.c:42:15: error: implicit declaration of function ‘mount’ [-Wimplicit-function-declaration] 42 | ret = mount("", "/", NULL, MS_PRIVATE | MS_REC, 0); | ^~~~~ pid_max.c:42:36: error: ‘MS_PRIVATE’ undeclared (first use in this function); did you mean ‘MAP_PRIVATE’? 42 | ret = mount("", "/", NULL, MS_PRIVATE | MS_REC, 0); | ^~~~~~~~~~ | MAP_PRIVATE pid_max.c:42:36: note: each undeclared identifier is reported only once for each function it appears in ... The fix seems to be including sys/mount.h which brings in the missing defines and missing definition mount function.
