Solaris下编译Tomcat4.1.x结果与官方发布不同，求教！

我在编译完Tomcat4.1.29后对照官方网站下载的二进制包有区别，少了几个jar文件：
/common/lib/jdbc2_0-stdext.jar
/common/lib/jndi.jar
/common/endorsed/xercesImpl.jar
/common/endorsed/xmlParserAPIs.jar

我是用ant1.6.1编译的，以下是编译过程中的部分信息

...
copy-activation.jar:

因为不知道编译后少掉这几个jar文件是否会产生什么负面影响，请高手解释一下原因，说明这样的后果和解决办法。
不胜感谢！
