[Bug classpath/31927] New: gnu_java_nio_VMChannel.c(available) does not work for FreeBSD

[kaz at maczuka dot gcd dot org]

gnu_java_nio_VMChannel.c has this code:

  if (ioctl (fd, FIONREAD, &avail) == -1)
      JCL_ThrowException (env, IO_EXCEPTION, strerror (errno));

But FreeBSD's ioctl with FIONREAD fails because of errno = 25
(Inappropriate ioctl for device).

native/jni/native-lib/cpio.c has a similar code:

#if defined (FIONREAD)
  ssize_t n;

  if (ioctl (fd, FIONREAD, (char *)&n) != 0)
        return errno;

This checking for FIONREAD does not work for FreeBSD because
FreeBSD does have FIONREAD but it cannot be used for calculating
available bytes.
