(AC_LANG_INT_SAVE(C)): Allow expression to return any value that can

fit into unsigned long (not int, as before).  Check for output errors.

From Bruno Haible:

(AC_LANG_INT_SAVE(C)): Always include <stdio.h> and
<stdlib.h>. Evaluate the expression in an extra function before these
includes. Call fprintf "%d" only after ensuring the argument is of
type 'int'.  Reported by Wayne Chapeskie <waynec@spinnaker.com>.
