It is kind-a surprising that we do not need to play with any
Makefile macros for this implementation.

If some unknown version (either in the long past or in the future)
of OpenSSL does not define the constant, this is just compiled out
and that would be OK.

If some unknown version of OpenSSL does define it but not as a
string constant, it would break the build, e.g.,

	#define OPENSSL_VERSION_TEXT 2 plus 4 is 6

We could stringify it ourselves, but that is probably not worth
worrying about.

Will queue.  Thanks.
