If I read this correctly, the carry handling is depending on integer
overflow wrapping around, which is not actually defined behavior in
C, although most platforms do handle it that way. Do we have an
MPI_LIMB_MAX constant analogous to INT_MAX but for mpi_limb_t instead
of int?
Limbs are unsigned integers and unsigned integer overflow is defined
behavior.
Aha... I had forgotten that unsigned integers do wrap. Thank you.
