Compiler CC and gcc under Unix are able to link each

I've tested that comiler CC and gcc under Solaris 10 are able to link each. It means, a software could be compiled partly in CC, and other in gcc. The could link the generated .so files rightly.

It is very useful while 2 teams need to cooperate, to combine.

测试结果：在Solaris 10 下，使用gcc编译出来的程序可以链接CC编出来的.so库，反之亦然。

在两个团队需要合作，需要集成为一个软件，或者一个团队需要用到第三方的.so库时，这非常有用。
