Hi,
I noticed that a patch addressing the same issue has been proposed by
Michal Suchanek:
https://lore.kernel.org/linuxppc-dev/z86liwlwp5wvr...@kitsune.suse.cz/T/#t
The existing patch addresses the compilation error by modifying the Makefile
to use `gnu11` with `BOOTTARGETFLAGS`. This is a practical approach to avoid
the error in the short term.
This patch builds on that work by providing a long-term solution that ensures
compatibility with C23 while maintaining backward compatibility. Specifically:
- It uses `__STDC_VERSION__` to conditionally define the `bool` typedef only
for pre-C23 standards.
- It ensures that the code is future-proof and ready for upcoming C23
standards,
where `bool`, `true`, and `false` are reserved keywords.
- It avoids reliance on compiler-specific flags, making the code more
portable
and standards-compliant.
Changlog:
- Adding version check via __STDC_VERSION__
- If __STDC_VERSION__ < C23, 'typedef int bool' is defined as usual
- If __STDC_VERSION__ >= C23, the typedef redundancy is removed
The patch has been tested with:
- gcc (GCC) 15.0.1 20250228 (Red Hat 15.0.1-0)
- gcc (GCC) 14.2.1 20250110 (Red Hat 14.2.1-7)
Thanks,
