$.2 idea:

Add two macros that allows you to write:

  size_t len;

  printf ("len: %" PRIz "\n", PRIzCAST(len));

If the system printf supports %zu, or if the gnulib printf module that
supports %zu is enabled, the macros would be defined as:

#define PRIz "zu"
#define PRIzCAST(x) (x)

Otherwise, the macros would be defined as:

#define PRIz "lu"
#define PRIzCAST(x) ((unsigned long)x)

Thoughts?

I'm not sure this is a good idea, the code is slightly unreadable.  On
the other hand, the current code is slightly unreadable already:

  printf ("len: %lu\n", (unsigned long) len);
