[SR-Users] clang compiler warnings

[Juha Heinanen]

I just made a test and, for sure, clang warns about unused variables:

$ clang -Wunused-variable -I/usr/include/re -I/usr/include/baresip -lbaresip -lrem -lre baresip.c 
baresip.c:48:6: warning: unused variable 'unused' [-Wunused-variable]
        int unused;
            ^
1 warning generated.
