In older glibc (like 2.28 on CentOS Stream 8) there is no wrapper
for the gettid() syscall, so we need to provide our own.
../src/libsystemd/sd-journal/journal-send.c: In function ‘close_journal_fd’:
../src/libsystemd/sd-journal/journal-send.c:88:25: error: implicit declaration of function ‘gettid’; did you mean ‘getgid’? [-Werror=implicit-function-declaration]
if (getpid() != gettid())
^~~~~~
getgid
../src/libsystemd/sd-journal/journal-send.c:88:25: warning: nested extern declaration of ‘gettid’ [-Wnested-externs]
cc1: some warnings being treated as errors
