Correct - our situation is Arnd's case b).

But my understanding is that for c) glibc has to modify the generic
syscalls wrapper (like clock_gettime/nanosleep/settime, etc.), and
for b) we also need to do that first.  But currently we are stuck at
the point where the __ASSUME_TIME64_SYSCALLS flag is not accepted /
pulled.

So b) and c) align in development...

Best regards,

Wolfgang Denk
