   9 + * compat hacks in case libc and kernel get out of sync:
  10 + *
  11 + * glibc 2.4 and uClibc 0.9.29 introduce IPV6_RECVPKTINFO etc. and change IPV6_PKTINFO
  12 + * This is only supported in Linux kernel >= 2.6.14
  13 + *
  14 + * This is only an approximation because the kernel version that libc was compiled against
  15 + * could be older or newer than the one being run.  But this should not be a problem --
  16 + * we just keep using the old kernel interface.
  17 + *
  18 + * these are placed here because they're needed in all of socket.c, recv.c and send.c
