This does not work.  Often the code that calls OpenSSL_add_all_algorithms()
is not the code that knows which algorithms will be used (think
scripting languages).  Having a single call that adds all the
algorithms or just the non-legacy algorithms can work, hance Matt's
suggestion of a #define that selects between two implementations,
and requires linking with the legacy library.
