python39 is affected; python35 and python36 are not affected.

py37-pycryptodome and py38-pycryptodome are additional examples of ports failing to build on 10.6 because of this issue.

    initial v4  
    1 Python 3.x ports build using `-Wno-unused-result`; this argument gets saved in `CFLAGS` and other variables in _sysconfigdata!__darwin_darwin.py, and is used again when building ports for Python modules. On macOS 10.6, Python itself is built using an alternative compiler (e.g. MacPorts' clang 3.7 or clang 9.0) which recognizes `-Wno-unused-result`, but modules (e.g. `py3x-cchardet`) might try to build using a system compiler (e.g. gcc 4.2) which doesn't recognize the option:

    6 Possibly related to #56458. Possibly present in `python35` or earlier but haven't checked. (I personally am not using macOS 10.6.)
