Confirmation Checklist

• The package is maintained in this repository.
• I understand that issues related to the base OpenWrt repository or LuCI repository will be closed.
• I am reporting an issue for OpenWrt, not an unsupported fork.

Start with filters.c, especially get_filter_function and execute_content_filters, and reproduce the failure with make -j1 V=s packages/privoxy/compile. Compare the filter function declarations and assignments involved in the reported diagnostics. Done means the privoxy package compiles successfully without these errors.
