Won't this be a very disruptive change to distributions, whose system libraries have not switched to 64-bit time_t on 32-bit? gnulib should not try to force a different distribution default. I'm worried that this will lead to distributions abandoning 32-bit i386 support altogether because the support cost is too high=E2=80=94and you can= 't even run legacy binaries anymore.
