That was for gnulib.
The patch below pulls the fix into coreutils.

I'll probably make a release in the next two weeks,
partly in order to forestall bug reports when more
countries switch.  Besides, we're already up to three
"Bug fixes", even if they're all minor.

** Bug fixes

  rm -rf DIR would fail with "Device or resource busy" on Cygwin with NWFS
  and NcFsd file systems.  This did not affect Unix/Linux-based kernels.
  [bug introduced in coreutils-8.0, when rm began using fts]

  tac no longer fails to handle two or more non-seekable inputs
  [bug introduced in coreutils-5.3.0]

  tail -f no longer tries to use inotify on GPFS file systems
  [you might say this was introduced in coreutils-7.5, along with inotify
   support, but the GPFS magic number wasn't in the usual places then.]

Subject: [PATCH] tests: update gnulib to latest to avoid FP DST-related test
 failure

Otherwise, "make check" would fail after e.g., a CEST-to-CST
daylight savings transition.
