* defs.h (widen_to_ull): New macro. * dirent.c (print_old_dirent, SYS_FUNC(getdents)): Use it in place of explicit casts to unsigned long long. * io.c (print_lld_from_low_high_val): Likewise. * lseek.c (SYS_FUNC(llseek)): Likewise. * printsiginfo.c (print_si_info): Likewise. * printstat.h (DO_PRINTSTAT): Likewise. * sysinfo.c (SYS_FUNC(sysinfo)): Likewise. * times.c (SYS_FUNC(times)): Likewise. * fetch_struct_statfs.c (ASSIGN_NUMBER): Remove. (fetch_struct_statfs, fetch_struct_statfs64): Replace ASSIGN_NUMBER with widen_to_ull.
