Bugzilla Bug 113558

When compiling smpeg with gcc-4.1, the build of "audio/MPEGaudio.cpp" fails
with 
"Play_MPEGAudioSDL not in scope".  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.
