sys/cdefs.h from libbsd neglects to define __unused, with this comment:
/* Linux headers define a struct with a member names __unused.
* Debian bugs: #522773 (linux), #522774 (libc).
* Disable for now. */
One of those reports has been closed for about 9 years, and the other is
marked "wontfix". sys/tree.h still refers to the macro, which can cause
non-obvious error messages:
In file included from test.c:3:
test.c:29:1: error: expected ‘;’ before ‘static’
29 | RB_PROTOTYPE_STATIC(tree_head, tree_node, rb_entry,
tree_node_cmp);
| ^~~~~~~~~~~~~~~~~~~
I don't see any particular reason why it has to use the exact macro name
used on BSD; so, I recommend replacing all references with LIBBSD_UNUSED
and re-enabling the part of cdefs.h that would define it.
(If the name "__unused" later becomes available, and anyone still cares,
a "#define __unused LIBBSD_UNUSED" can be added.)
