Test failed.
so it is to do with an old version of the tls protocol used by libcurl, and as it looks like the amiga version was built with libcurl embedded i dont think its a simple case of getting the latest version of libcurl.
i would assume, not knowing amiga programming that well, that GFXBench2D would need to be recompiled with the new libcurl, or use the libcurl sobjs.
