 config: fix SSL detection
 
-The @WEBSOCK_HAVE_SSL@ is not replaced at configure time, and even if
-it was, it would be replaced by an empty string if openssl is disabled,
-thus still defining WEBSOCK_HAVE_SSL when we would not want it.
+The @WEBSOCK_HAVE_SSL@ is replaced at configure time with either a 1 or 0.
+The rest of the code is simply checking to see if WEBSOCK_HAVE_SSL is
+defined at all. Using a #undef WEBSOCK_HAVE_SSL will cause configure
+to either comment it out or change the line to
+"#define WEBSOCK_HAVE_SSL 1".
 
-Instead, rely on config.h, which is properly generated by ./configure,
-to provide the information about whether openssl is enabled or not.
