Hi,
  Thanks to Kevin Fall, Christoph Haenle and other people for your
great help.

I tried to run the command but I couldn't find the file where
"IP_MULTICAST_LOOP" is defined.

I replaced the command and this one has been solved.

I also couldn't find the file where it is defined.

I'm installing the ns on a sparc-sun-sunos4.1.3 machine. I tried to
include a couple of header-files to net-ip.cc but everything was in
vain. I wonder whether anybody has faced the same problem during the
installation of ns on sparc-sun-sunos4.1.3 machines. Are there any
tries that I can do to solve these problems?

I intend to run wireless TCP simulations using ns. I wonder whether
the `net-ip.o' is compulsory for my simulation. If not, I may try to
edit the Makefile so that the compilation of `net-ip.o' is
omitted. 

Could someone please help me again? Sorry for bothering you all so
much. Your help would be much appreciated.
