You should take a look at http://www.w3.org/Library/Examples/wwwssl.c, in 
particular the following fragment,

    /* Set the SSL protocol method. By default, it is the highest
       available protocol. Setting it up to SSL_V23 allows the client
       to negotiate with the server and set up either TSLv1, SSLv3, 
       or SSLv2 */
    HTSSL_protMethod_set (HTSSL_V23);

    /* Set the certificate verification depth to 2 in order to be able to
       validate self signed certificates */
    HTSSL_verifyDepth_set (2);

    /* Register SSL stuff for handling ssl access */
    HTSSLhttps_init(YES);

Since you are using c++, the libwww function prototypes will need to be 
declared as being external c calls.  For example, around your includes,

  #include <iostream.h>

  extern "C" {
  #define BOOL int
  #include <HTChunk.h> 
  }

  void main( int argc, char** argv ) {
    HTChunk * c = HTChunk_new ( 1024 );
    int s = HTChunk_size ( c );
    cout << "Chunk allocated at " << c << ", " 
         << "of size " << s << "." << endl;
  }

We may do this is to add a decoration to the top of the libwww headers
like,

    #ifdef __cplusplus
    extern "C" {
    #endif

and the corresponding 

    #ifdef __cplusplus
    }
    #endif
