Yep, and that's why many newer systems are switching to 64-bit time_t.
But changing the size of size_t is an ABI difference, so not one that you
can easily port to older kernels.

Not a bug in coreutils, but an inherent limitation in your kernel. Just
like the old limitation that you couldn't have a file larger than 2GB
until you upgraded to a kernel with 64-bit off_t support.
