* Standard uint<N>_t types must not contain any any extraneous bits, but that

* 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.
