SBCL 2.3.11 (and many older versions) don't build on Freebsd 14.

[David J. Fiander]

When I try to build SBCL on FreeBSD 14, it fails to compile src/runtime/bsd-os.c:

bsd-os.c:290:50: error: incompatible function pointer types passing '__siginfohandler_t *' (aka 'void (*)(int, struct __siginfo *, void *)') to parameter of type 'interrupt_handler_t' (aka 'void (*)(int, struct __siginfo *, struct __ucontext *)') [-Wincompatible-function-pointer-types]
                                                 (__siginfohandler_t *)
                                                 ^~~~~~~~~~~~~~~~~~~~~~
./interrupt.h:124:64: note: passing argument to parameter 'handler' here
extern void ll_install_handler(int signal, interrupt_handler_t handler);

I'm not sure why there's an explicit cast to (__siginfohandler_t *) on line 290 of bsd-os.c, because it's calling ll_install_handler(), which is an internal SBCL runtime function that just takes an interrupt_handler_t as an argument. Removing the FreeBSD-specific conditional code compiles clean and passes all the tests.

Can you create a patch?
