Could you give more details of your analysis for <sys/cdefs.h>, for what 
headers under what feature test macros use any of the relevant macros from 
<sys/cdefs.h>?  (Since certainly <sys/cdefs.h> is used in lots of 
installed headers that don't and can't define size_t in standard C modes, 
so the question is when the particular macros therein that would use 
size_t themselves get used.)
