关于oracle开发包使用的一个问题

关于oracle开发包使用的一个问题
我的solaris是32位的，用到的开发包是： 
instantclient-sdk-solaris-x86-6432-10.2.0.2-20060526.zip 
instantclient-basic-solaris-x86-6432-10.2.0.2-20060526.zip 
看上去这个包好像是32和64位机器都可以用，
instantclient-basic-solaris-x86-6432-10.2.0.2-20060526.zip 解压后只有一个版本(没有分32或64位)的.so文件
 
请问使用这个包时候需要定义宏来标识是32位还是64的吗？
