-   The INT_<op>_RANGE_OVERFLOW macros return 1 if the corresponding C
-   operators might not yield numerically correct answers due to
-   arithmetic overflow.  They do not rely on undefined or
-   implementation-defined behavior.  Their implementations are simple
-   and straightforward, but they are harder to use and may be less
-   efficient than the INT_<op>_WRAPV, INT_<op>_OK, and
-   INT_<op>_OVERFLOW macros described below.
-
-   Example usage:
-
-     long int i = ...;
-     long int j = ...;
-     if (INT_MULTIPLY_RANGE_OVERFLOW (i, j, LONG_MIN, LONG_MAX))

-
-   Restrictions on *_RANGE_OVERFLOW macros:
-
-   These macros do not check for all possible numerical problems or
-   undefined or unspecified behavior: they do not check for division
-   by zero, for bad shift counts, or for shifting negative numbers.
-
-   These macros may evaluate their arguments zero or multiple times,
-   so the arguments should not have side effects.  The arithmetic
-   arguments (including the MIN and MAX arguments) must be of the same
-   integer type after the usual arithmetic conversions, and the type
-   must have minimum value MIN and maximum MAX.  Unsigned types should
-   use a zero MIN of the proper type.
-
-   Because all arguments are subject to integer promotions, these
-   macros typically do not work on types narrower than 'int'.
-
-   These macros are tuned for constant MIN and MAX.  For commutative
-   operations such as A + B, they are also tuned for constant B.  */

-   The INT_<op>_OVERFLOW macros return 1 if the corresponding C operators

-   The INT_<op>_WRAPV macros compute the low-order bits of the sum,
-   difference, and product of two C integers, and return 1 if these
-   low-order bits are not numerically correct.
-   These macros work correctly on all known practical hosts, and do not rely
-   on undefined behavior due to signed arithmetic overflow.
-
-   Example usage, assuming A and B are long int:
-
-     if (INT_MULTIPLY_OVERFLOW (a, b))
-       printf ("result would overflow\n");
-     else
-       printf ("result is %ld (no overflow)\n", a * b);

-     printf ("result is %ld (%s)\n", result,

-
-   Restrictions on these macros:
-
-   These macros do not check for all possible numerical problems or
-   undefined or unspecified behavior: they do not check for division
-   by zero, for bad shift counts, or for shifting negative numbers.
-
-   These macros may evaluate their arguments zero or multiple times, so the
-   arguments should not have side effects.
-
-   The WRAPV macros are not constant expressions.  They support only
-   +, binary -, and *.
-
-   Because the WRAPV macros convert the result, they report overflow
-   in different circumstances than the OVERFLOW macros do.  For
-   example, in the typical case with 16-bit 'short' and 32-bit 'int',
-   if A, B and R are all of type 'short' then INT_ADD_OVERFLOW (A, B)
-   returns false because the addition cannot overflow after A and B
-   are converted to 'int', whereas INT_ADD_WRAPV (A, B, &R) returns
-   true or false depending on whether the sum fits into 'short'.
-
-   These macros are tuned for their last input argument being a constant.
-
-   Return 1 if the integer expressions A * B, A - B, -A, A * B, A / B,
-   A % B, and A << B would overflow, respectively.  */
