That function is a friend of the MPEGAudio class. I suspect new scoping rules caused this to break, but I'm not sure. I managed to get it working by putting a "using namespace std;" at the top of the file and declaring those functions before they are "befriended". I will attach a patch that worked for me once this bug has been filed. Reproducible: Always Steps to Reproduce: 1. Install GCC-4.1 2. Try to compile smpeg 3. Watch Rome Burn. Actual Results: Compile failed. Expected Results: Compile should succeed.
