平台：
aix5.3.0.0
sybase 12.5.4 32位
rs6000
SYBPLATFORM=rs6000已经定义
描述：
从aix4.3.2.0 sybase 12.0 移植到 aix 5.3.0.0 sybase 12.5.4，在aix4.3.2.0 sybase 12.0上面没有出现问题，
顺利编译，但在新的平台下:sybase的sample/esqlc下的例子可以编译成功，但是编译自己的应用的时候报错，预编译没事，
ld的时候报错：
ld: 0711-317 ERROR: Undefined symbol: .cs__delete_thread_msg__FP10_cscontext
ld: 0711-345 Use the -bloadmap or -bnoquiet option to obtain more information.
我看了我门平台自己的应用和makefile，程序中也都include了头文件/OCS-12_5/include/sybhesql.h和sybtesql.h，
make的要素和sample里面的本质是一样的，只是多连接了我们应用自己的东西，make以及makefile如下，我觉得可能是连进来的
我们自己的静态库libpub.a有问题，但是我看了我们生成静态库libpub.a的makefile和程序，没有什么错，而且里面用到的.h都有，
都是没有什么异常的：

请大家指点，找了很久的错，都找不到原因
