But in the meantime, everyone else who wanted to run on mingw would be
left high and dry, as coreutils wouldn't build.

Is there some middle ground here, where we can generate a warning for
people building on old-fashioned systems without sub-second clocks,
without refusing to build coreutils entirely?  Admittedly warnings are
often ignored, but I hope you get the idea.

Perhaps something like the following?

#ifdef OK_TO_USE_1S_CLOCK
  ts->tv_sec = time (NULL);
  ts->tv_nsec = 0;
#else
  #error "Only 1-second nominal clock resolution found.  Is that intended?  If 
so, recompile with -DOK_TO_USE_1S_CLOCK"
#endif
