I worry that this puts the incremental cart before the incremental
horse, at least for portable applications. If we take the _TIME_BITS=64
approach, portable applications should add the equivalent of "#define
_TIME_BITS 64" to their config.h files or ihatever, because they should
be Y2038-safe. But if glibc development is incremental so that some
time_t uses are glitchy when _TIME_BITS=64, these applications will have
problems. Conversely, if glibc doesn't publicize the time_t changes
until they're ready (which I think is the intent), the _TIME_BITS=32
approach would be less hassle overall for portable applications; they
won't have to change their source code.
