ugh, right.

two things:

- i typo'd that, and it's off by one (should be lld on the time_t not the
  suseconds_t. same below.)
- glibc only supports _TIME_BITS=3D64 on 2.34 or newer. debian bullseye (11=
)
  has 2.31, meaning that this would not work there anyway. iirc we could do
  some sort of ifdef stuff and use autoconf (assuming a new enough autoconf=
),
  but i'll just abandon this for now, and perhaps revisit this when '2.34' =
is
  considered new enough for nobody to care about. not a huge fan of adding =
macro
  checks..

sorry for the noise.
