mus_.cpp: In member function 'virtual bool sidTune::MUS_fileSupport(const void*, udword)':
mus_.cpp:76:38: error: array subscript has type 'char' [-Werror=char-subscripts]
                 infoString[line][si++] = c;  // copy to info string
                                      ^

Using a char here is ok, but GCC cannot prove it. It is used only in the
range [0, 31].
