* Bug 193 (local-bugzilla-354):
*
* SUMMARY: storing opt. results of Not/NAnd/NOr into Buffer Field in 32-bit mode can soil the higher bits of BF
*
* In 32-bit mode optional storing of the result of any of
* Not, NAnd, and NOr ASL operators to Buffer Field of more
* than 4 bytes in length can produce non-zero bits outside
* the first 32 bits (though zeros are expected):
