MarsSeed [1] filed a deletion request for lib32-libmodbus-dev [2]: I suggest this outdated dev version lib32 library can be deleted. Nothing on AUR depends on it. Modbus protocol compliant device owners can use the native-build (AUR/libmodbus) or (AUR/libmodbus-dev) version of this library to work with those devices. Safe to delete; no impact.
