9.6.1 Fast 32-bit arithmetic

The INT32 API provides a way to perform optimal raw 32-bit arithmetic. Note that, unlike Lisp integer types, this is modulo 2^32 like the C int type.

The Lisp type sys:int32 reads 32 bits of memory, like (signed-byte 32) , but the data is in sys:int32 format for use with the INT32 API.
