Changes between 0.9.3a and 0.9.4
+ *) When bntest is run from "make test" it drives bc to check its
+ calculations, as well as internally checking them. If an internal check
+ fails, it needs to cause bc to give a non-zero result or make test carries
+ on without noticing the failure. Fixed.

*) DES library cleanups.
