Fix compilation under clang

2026-03-13T00:11:32Z

Makes uses of _FORTIFY_INLINE and _FORTIFY_POS0 in sys/select.h, as clang complains about __gnu_inline__ in some cases. An issue which is already fixed with the shared macros. It was reported it: - https://gitlab.alpinelinux.org/alpine/aports/-/issues/18015 - https://gitlab.alpinelinux.org/alpine/aports/-/issues/18000 Co-Authored-By: Sertonix

avoid extension with clang

It seems useless and triggers 'error: expected external declaration'

Make use of __builtin_dynamic_object_size

2025-10-31T21:16:21Z

GCC and Clang provide __builtin_dynamic_object_size (see documentation: https://gcc.gnu.org/onlinedocs/gcc/Object-Size-Checking.html), so we should make use of it when its available.

Don't use extension in C++ code

A few important notes: * __extension__ is a GNU C "alternate" keyword, not a C++ keyword.[1] * __extension__ is designed to work on "expressions"; it does work on #include_next in C mode, but it has no effect in C++ mode; the warning will still appear, if enabled, even with __extension__ preceding #include_next. This is because #include_next is not considered an expression in C++, so the compiler attaches __extension__ to the first expression of the header. All of this leads us to a build failure while building at least all Mozilla software. Moz has an alternate -isystem dir searched before /usr/include that overrides some headers, including . The first statement in each of these headers is a #pragma, and since __extension__ is looking for an expression, and #pragma is a "null" expression, we end up with the following error: dist/system_wrappers/features.h:1:9: error: '#pragma' is not allowed here Since __extension__ has no effect on #include_next in C++ mode anyway, and since it can cause breakage, this commit omits __extension__ in C++ mode.
