I notice warnings that I think are caused by this patch on some buildfarm
members, eg

(bowerbird and hamerkop are showing the same).
My first thought about it was that this bit is busted:
+#ifndef USE_OPENSSL
+ RAND_poll();
+#endif
The obvious problem with this is that if !USE_OPENSSL, we will not have
pulled in openssl's headers.
However ... all these machines are pointing at line 96, which is not
that one but the one under "#if defined(USE_OPENSSL)". So I'm not sure
what to make of that, except that a bit more finesse seems required.
