    _______________________________________________________

Details:

I just tried to compile the package with clang. It said:

src/utils/addftinfo/addftinfo.cpp:119:5: warning: variable 'i' is incremented
both in the loop header and in the loop body [-Wfor-loop-analysis]

Source code is

  for (i = 1; i < argc && argv[i][0] == '-'; i++) {
...
    i++;
  }
