[ns] Question about wireless support in ns 2.1b7 / nam 1.0a9
[LinuxPPC 2.2.16 / 224MB RAM / gcc 2.95.2 / glibc 2.1.3-4b]
I'm trying to merge the mcast.tcl and wireless2.tcl scripts to simulate a
multicast to a group of wireless machines, but keep having problems
creating the base station node (line 139) once I add the "-multicast on"
flag to the simulation creator. Here is the code:

# updated to use -multicast on and allocaddr by Lloyd Wood
#
# Simple multicast test. It's easiest to verify the
# output with the animator.
# We create a four node start; start a CBR traffic generator in the center
# and then at node 3 and exercise the join/leave code.
