configure already has a similar issue for isinf(). (I thought there

We could just duplicate that logic, or maybe it's time to wrap it
up in an autoconf macro?

True as far as HEAD goes. What I'd like to know is whether not
realizing that SSL_clear_options is present causes any functional
issues that would justify back-patching a fix.
