Comment (by RobK88):

 Thanks Ken for the feedback.  I will take a closer look and see if we can
 patch the code.

 Please note that two of the errors disappear if one uses `clang-15` or
 earlier to build `geany`.
 See https://trac.macports.org/ticket/69791
 As a result only the `scandir` error remains.

 Here is the output when building `geany` on Lion using `clang-15`:
