[PATCH 2/2] libc/features.h: Make code match documentation
Simon Barth

Fri Nov 14 22:00:44 GMT 2025
The documentation states that _GNU_SOURCE enables "all of the above
plus GNU extensions.". Furthermore the documentation states that
_DEFAULT_SOURCE would enable POSIX-1.2008 with BSD and SVr4 extensions.
The code did different things though:
* For _GNU_SOURCE it only enabled POSIX.1-2008 but it should have been the
highest available one, POSIX.1-2024.
* For _DEFAULT_SOURCE it enabled POSIX.1-2024.
Let's use the highest available POSIX standard possible and fix
documentation where necessary.
