The "recursive:" kwarg is available in the targeted minimum version of
meson, and is basically required if you want to not emit warnings and
maybe error with --fatal-meson-warnings.
There are two basic solutions to this problem:
- The current default behavior is false, so explicitly opt in to that
value. None of these internal libraries use recursive objects anyway.
- Use link_with to link to the static library directly, rather than the
extracted objects.
Option 2 is what used to be done before commit
62af03bda8, but it only works with meson
>=0.52 and previously had buggy behavior.
Since the minimum version of meson is now 0.52, it is safe to revert
that commit and go back to using link_with, and therefore option 2 is
chosen.

Despite their type, the values returned will always be ≥ 0. It’s
unfortunate they weren’t declared with an unsigned type, but we can’t
change that now without breaking API.

MSVC supports AddressSanitizer as well via "/fsanitize=address" option,
but __lsan_ignore_object() equivalent feature is not supported.
Note that there's __declspec(no_sanitize_address) specifier which
provides a similar feature but that's not runtime behavior
so it's not directly applicable to g_ignore_leak() family.
