The CI, now with gcc 14, reports a compilation error on Solaris 11 OmniOS:
In file included from ../../gltests/test-accept.c:21:
../../gltests/test-accept.c:22:18: error: initialization of 'int (*)(int,
struct sockaddr *, socklen_t *)' {aka 'int (*)(int, struct sockaddr *,
unsigned int *)'} from incompatible pointer type 'int (*)(int, struct sockaddr
* restrict, void *)' [-Wincompatible-pointer-types]
22 | SIGNATURE_CHECK (accept, int, (int, struct sockaddr *, socklen_t *));
| ^~~~~~
With older gcc versions, I see these warnings:
../../gltests/test-accept.c:22:18: warning: initialization of 'int (*)(int,
struct sockaddr *, socklen_t *)' {aka 'int (*)(int, struct sockaddr *,

It's not worth working around these declarations (that are wrong w.r.t. POSIX),
because hardly anyone uses these functions through function pointers.
So, let me just document the problem and avoid a compilation error:
