opensbi failed to build

[ElyesH]

I've used c23 dialect to build test coreboot and got the following error:
CC ramstage/arch/riscv/opensbi.o In file included from 3rdparty/opensbi/include/sbi/fw_dynamic.h:46, from src/arch/riscv/opensbi.c:8: 3rdparty/opensbi/include/sbi/sbi_types.h:47:33: error: two or more data types in declaration specifiers 47 | typedef int bool; | ^~~~ 3rdparty/opensbi/include/sbi/sbi_types.h:47:1: error: useless type name in empty declaration [-Werror] 47 | typedef int bool; | ^~~~~~~ cc1: all warnings being treated as errors make[2]: *** [Makefile:423: /cb-build/coreboot-gerrit.0/gcc/EMULATION_QEMU_RISCV_RV64_/ramstage/arch/riscv/opensbi.o] Error 1 make[2]: Leaving directory '/home/coreboot/node-root/workspace/coreboot-gerrit'

what are the make parameters that make opensbi fail to build?

The problem is that you unconditionally typedef bool in this file opensbi/include/sbi/sbi_types.h!
C23 already have bool .

Please use something like :
#if __STDC_VERSION__ <= 201710L typedef _Bool bool; #endif
