-- Explicitly cast memcpy() arguments to void*/const void* when copying raw
-- bytes of the non-trivially-copyable `DoF` struct (it has a user-defined
-- copy constructor), since newer Clang (21.x, as used on current FreeBSD)
-- turns this into a hard error (-Werror,-Wnontrivial-memcall) instead of a
-- warning; the raw byte copy itself is safe/intentional since DoF is a
-- simple wrapper around a single uint64_t with no virtual members.
