Log message:
        (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: 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'.
