将宏内行间的代码替换为注释的脚本

    最近看到一些代码中总是有者/* under construction !*/这样的注释，于是也想写出这样效果的脚本。

    如果原来的代码为：
#ifdef AAA//AAA
a = a + 1
#ifdef BBB//BBB
b = a + 1
#else //BBB
b = 100
#endif //BBB
c = 999
#endif //AAA

      想要达到的效果是：
#ifdef AAA//AAA
/* under construction !*/
#ifdef BBB//BBB
/* under construction !*/
#else //BBB
/* under construction !*/
#endif //BBB
/* under construction !*/
#endif //AAA

     最终的Python脚本程序如下，该脚本有一种情况下没有考虑，即同一行预编译语句中包含有多个宏控制下的处理，本脚本默认是不将代码修改为注释。
