glibc/libio/iofgetpos.c
Roland McGrath 3efdabe762 * libio/ftello.c (ftello): Use _IO_off64_t for type of POS.
Check for the result overflowing off_t and fail with EOVERFLOW.
	* libio/ioftell.c (_IO_ftell): Likewise.
	* libio/iofgetpos.c (_IO_new_fgetpos): Likewise.

	* login/logwtmp.c (logwtmp): If sizeof ut_tv != sizeof struct timeval,
	use a temporary timeval on the stack for gettimeofday and copy it.
	* login/logout.c (logout): Likewise.
	Reported by Steven Munroe <sjmunroe@us.ibm.com>.

	* sysdeps/unix/sysv/linux/bits/statfs.h (struct statfs):
	Use __SWORD_TYPE instead of int for member types.
	(struct statfs64): Likewise.
