I didn't remember I wrote this exact patch, but anyway the patch itself
is confusing.

The member 'feature' is described here. It still causes build warning?

Why adding a duplicated item would fix the warning?

The prototype is for dfl_fme_destroy_bridges(), why the warning?

Correct the plural form in description would fix the warning?
