My first attepmt was to do the whole thing with cpp macros.  However,
after giving it some thought, that could cause a number of problems;
one is that macros have zero type safety.  You can give those macros
exactly whatever without the compiler reacting, since a lot of casts
would be made in their expansion.  The other problem is applications
that link either with libdes or with openssl's libcrypto.  The latter
will very suddenly fail.

But, this isn't the end of the story.  On some architectures, there
are binary incompatibilities between openssl's libcrypto and libdes.
