I believe the C standard leaves the width of size_t open. When it speaks
about "an unsigned integer type", that does not necessarily mean it's
*the* "unsigned int" of which we could maybe expect that it's 32 bits wide.

FWIW, on my system, size_t is 64 bits wide, like unsigned long and unlike
unsigned int:

  $ echo -e '#include <stdio.h> \n #include <stddef.h> \n int main(void) { printf("%u\\n", sizeof(size_t)); }' | gcc -x c - && ./a.out
  8
