Sorry, you're right.  I was doing too many things in parallel.
Another attempt at reduction:

--
#include <limits.h> 
#include <stdint.h> 
#define CHECK_UNSIGNED(TYPE) \ 
  do { TYPE a; int b[(TYPE)-1 < 0 ? -1 : 1]; } while (0) 
#define CHECK_EXPR_TYPE(TYPE, EXPR) \ 
  do { __typeof__(EXPR) a; __typeof__((TYPE)0 + 0) *b = &a; } while (0) 
#define UNSIGNED_MAX_COND(TYPE, EXPR) \ 
  ((EXPR) == (TYPE)-1) 
#define CHECK_UNSIGNED_LIMITS_2(TYPE, MAX, MAXBD)               \ 
  CHECK_UNSIGNED(TYPE);                                         \ 
  CHECK_EXPR_TYPE(TYPE, (MAX));                                 \ 
  do { int a[(UNSIGNED_MAX_COND(TYPE, (MAX))                    \ 
              && (MAX) >= (MAXBD)) ? 1 : -1]; } while (0) 

void 
test_misc_limits (void) 
{ 
  CHECK_UNSIGNED_LIMITS_2(__SIZE_TYPE__, SIZE_MAX, 65535U); 
}
