   Can't you safely do this with casting to the (possibly unsigned) long
   type?  e.g.,
	   pid_t whatever;
	   ...
	   printf( "%lu\n", (unsigned long) whatever);
   A pain, but hardly a "can't".

You are not guaranteed that long is the widest integral type.  

   Oh, and what's that special ANSI format code for size_t?  I can't find
   it in 4.9.6.1; was it added after printing or am I just blind?

I was wrong; there is not such ANSI format code.  The one I was
thinking of is a GNU extension.
