 * Provide stdint.h-like type names and macros for 9, 18, and 36-bit unsigned
 * integer types.
 *
 * Standard uint<N>_t types must not contain any any extraneous bits, but that
 * cannot be guaranteed for these 9, 18, and 36-bit types when they are embedded
 * in larger 16, 32, and 64-bit host types.  For arithmetic on these types, use
 * the operations provided by pdp10-arith.h.
 *
 * Do not use these 18 or 36-bit types for file-level binary data structures,
 * instead use the pdp10-extint.h and pdp10-stdio.h facilities to explicitly
 * convert between file-level and host-level binary data structures.
