The glob might pass a different stat struct for gl_stat and gl_lstat when GLOB_ALTDIRFUNC is used. This requires add a new 64-bit time version that also uses 64-bit time stat functions. Checked on i686-linux-gnu and x86_64-linux-gnu. Reviewed-by: Carlos O'Donell <carlos@redhat.com> Tested-by: Carlos O'Donell <carlos@redhat.com>
