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