[Q] errors occured on tcp.h

[Juyoung Park <jypark@comsun.chungnam.ac.kr>]

Hello ns-users..

During installation ns 2.0-17b on FreeBSD 2.2.2 machine, some errors
related on  tcp.h have occured .
As below:

tcp.h:157: `TracedVar' was not declared in this scope
tcp.h:157: `v' was not declared in this scope
tcp.h:157: variable or field `trace' declared void
tcp.h:164: `TracedVar' was not declared in this scope
tcp.h:164: `v' was not declared in this scope
tcp.h:164: variable or field `traceVar' declared void
tcp.h:171: syntax error before `;'
tcp.h:172: syntax error before `;'
tcp.h:173: syntax error before `;'
tcp.h:174: syntax error before `;'
tcp.h:175: syntax error before `;'
tcp.h:219: syntax error before `;'
tcp.h:223: syntax error before `;'
tcp.h:229: syntax error before `;'
tcp.h:232: syntax error before `;'
tcp.h:237: syntax error before `;'

I checked  my system-related header files to find where the TracedVar
and TracedInt is located, but all in vain..

What the TracedVar and TracedInt means?
How can I solve with this problem?

Thanks in advance..
