Yes, that was my assumption too.  However, as you mentioned, any
portable program that accesses files should use AC_SYS_LARGEFILE these
days.

mkstemp and tempname already invoke AC_SYS_LARGEFILE, so there's
precedent for having copy-file and clean-temp do it as well.

I'd say that ultimately it's configure.ac's responsibility, but gnulib
modules can require AC_SYS_LARGEFILE as a matter of convenience and/or
documentation.  Admittedly this is wishy-washy, but it does describe
common practice.
