The macro already supports multiple parameter indices. Example:

extern int scandir (const char *dir, struct dirent ***namelist,
                    int (*filter) (const struct dirent *),
                    int (*cmp) (const struct dirent **, const struct dirent **))
     _GL_ARG_NONNULL ((1, 2, 4));

OpenGL macro names start with GL_. So if we choose the prefix _GL_ we're
not likely to collide.
