[Ns-developers] Don't use ns 2.30 under cygwin.

[Lloyd Wood]

If you have to use ns under cygwin, I would recommend the allinone 2.29 package over the allinone 2.30 package.

ns allinone 2.30 dumps core on even the simplest ftp transfer/lossmonitor scripts, where 2.29 runs and produces actual results just fine. This looks like a threading problem, if the "fatal error [..] called with threadlist_ix -1"messages to console about ns.exe are anything to go by.
