Re: [Xen-devel] Failure to build fs-backend with the most recent Xen Unstable ( revesion 19374)

[Boris Derzhavets <bderzhavets@xxxxxxxxx>]

Just to be able to compile fixed fs-backend.c :-

static void aio_signal_handler(int signo, siginfo_t *info, void *context)
{
    int ret;
    struct fs_request *request = (struct fs_request*) info->si_value.sival_ptr;
    int saved_errno = errno;
    ret = write(pipefds[1], &request, sizeof(struct fs_request *));
    errno = saved_errno;
}

It brings to next error seems unrelated to previous one :-

The error log from compiling the libSDL test is:
