That build failure happened with gcc 7.5. This fix looks promising:
Fix check_op(s) compilation failures on gcc 8 which eagerly tries to
instantiate std::underlying_type for non-num types. Before cpp20 using
std::underlying_t on non enum types is undefined behaviour.
I don't have NetBSD 9 / old gcc around to test...
