Doesn't this argue against _TIME_BITS=64 in general? It seems to be 
saying that one should just recompile for 64-bit, and never use 
_TIME_BITS=64.

Agreed.

That's a reasonable approach and if people want to do that they can, 
even with the latest Gnulib and the next version of Glibc.

However, people who want to run old binaries will surely stick to the 
32-bit-time_t i386 port, which means they won't use the 64-bit-time_t 
i386 port. So it's not clear to me that they will cotton to this approach.
