Yeah, for some reason those are commented out in the newer version.

If you are building source, you can remove the // from these two lines in main.cpp

                printf("testHash %s\n", testHash.ToString().c_str());
                printf("Hash Target %s\n", hashTarget.ToString().c_str());

That will show in your debug.log every time you find a test hash, and have it compare against the hash target.  If you see those, then yes, you are mining (and you can watch it happen if you  watch the debug.log file scroll)
