Subject: [PATCH] Resolve build failures in pipewire code

g++-13 complains:

SDL_pipewire.c:129:42: warning: assignment to “struct pw_main_loop *
(*)(struct pw_main_loop )" from incompatible pointer type "struct
pw_main_loop * ()(const struct spa_dict *)”
[-Wincompatible-pointer-types]
129 | #define SDL_PIPEWIRE_SYM(x) PIPEWIRE_##x = x
SDL_pipewire.c:148:5: note: in expansion of macro “SDL_PIPEWIRE_SYM”
148 | SDL_PIPEWIRE_SYM(pw_main_loop_new);


g++-14 complains:

SDL_pipewire.c:129:42: error: assignment to “struct pw_main_loop *
(*)(const struct pw_main_loop )" from incompatible pointer type
"struct pw_main_loop * ()(const struct spa_dict *)”
