The only `size_t' appearing in any 4BSD release is in <sys/types.h>.
I have copied this from the 4.0BSD release (where the file was not even
called types.h---this is from /usr/src/sys/h/param.h), dated no later
than 1980, i.e., before ANSI C committees were even even a gleam in
someone's eyes:

typedef struct { int r[1]; } *  physadr;
typedef int             daddr_t;
typedef char *          caddr_t;
typedef unsigned short  ino_t;
typedef int             swblk_t;
typedef int             size_t;
typedef int             time_t;
typedef int             label_t[14];
typedef short           dev_t;
typedef int             off_t;

Whether size_t should have been `unsigned int' even then is another
question entirely.  The point, however, is that the size_t found in
4BSD is not related to the size_t found in the dpANS, and hence not
conformant.
