It seems that the newer GCC versions have changed the prototype. I've just tested `esp32c3-devkit:nsh` with `riscv64-unknown-elf-gcc` version **10.2** and it also reported the same warning. **Update**: `gcc version 9.2.1 20191025 (release) [ARM/arm-9-branch revision 277599] (GNU Tools for Arm Embedded Processors 9-2019-q4-major)` builds fine as well. Maybe we need something like `__GNUC__ < 10` to enable support for both types of prototypes. -- This is an automated message from the Apache Git Service.
