2 ** Random bits about coding standards and portability
5 You must cast the result of malloc on AIX.
6 It's even better to use gras_new when possible.
9 If possible, avoid size_t and use unsigned long instead.
11 #include <sys/types.h> in all files manipulating size_t
12 do cast it to unsigned long before printing (and use %lu)
16 PRINTF pointer difference
17 printf ("diff = %ld\n", (long) (pointer2 - pointer1));
