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—and you can't
even run legacy binaries anymore.

Thanks,
