Yes, I am suggesting to just remove both USE_*_RANDOM flags, and use
the following structure instead in pg_strong_random.c for both the
init and main functions:
#ifdef USE_OPENSSL
    /* foo */
#elif WIN32
    /* bar*/
#else
    /* hoge urandom */
#endif

And complain in configure.ac if we miss urandom for the fallback case.

Now, it would not be the first time I suggest something on this thread
that nobody likes :)
