mr3smp fails to compile with clang

[GoogleCodeExporter]

What steps will reproduce the problem?
1. download mp3smp-version-1.2
2. edit make.inc (change compiler from gcc to clang)
3. execute make

What I get:

What is the expected output?

Something along the lines of what I get with gcc, or in other words a working 
program.
