NixOS switched. And they're source-based, but with actual dependency tracking and all the (insanely complex) machinery needed to allow different programs to use different C library versions simultaneously. `printf("sizeof (time_t) = %zu, %zu bits", sizeof (time_t), sizeof (time_t) * CHAR_BIT);` gives you the size in bytes and in bits. Needs time.h, stddef.h, and stdio.h.
