	is now u_int, not int.
	(struct XDR.x_handy): Now u_int, not int.
	* sunrpc/xdr_mem.c: Include <limits.h>.
	(xdrmem_getlong, xdrmem_putlong, xdrmem_getbytes, xdrmem_putbytes,
	xdrmem_inline, xdrmem_getint32, xdrmem_putint32):
	x_handy is now unsigned, not signed.
	Do not decrement x_handy if no change is made.
	(xdrmem_setpos): Check for int overflow.
	* sunrpc/xdr_sizeof.c (x_inline): 2nd arg is now unsigned.
	(xdr_sizeof): Remove cast that is now unnecessary, now that
	x_handy is unsigned.
