I’d like to ping the patch at
https://gcc.gnu.org/pipermail/gcc-patches/2024-January/644134.html
The original proposal by Iain was:

extern "C" {
but it seems we can’t use __has_include. However, other code in GCC treats
<sys/types.h> as available on all targets. See unconditional inclusion in
gcc/system.h and gcc/tsystem.h. The latter even says:
/* All systems have this header. */
#include <sys/types.h>
So: would an unconditional inclusion be suitable? I’ve tested on linux and
darwin with no issues:

Thanks,
