Use typeof(sizeof(...)) to define a size_t. This stops gcc complaining

about format errors for %zX arguments.

src/arch/i386/include/stdint.h

 #ifndef STDINT_H
 #define STDINT_H
 
-typedef unsigned long		size_t;
+typedef typeof(sizeof(int))	size_t;
 typedef signed long		ssize_t;
 typedef signed long		off_t;
