在预处理期间，模型被确认并且确认错误根据移植计划中定义的指令被解决。
During pre-processing the models were validated and the validation errors resolved according to instructions defined in the migration plan.
这是因为实际的源代码和变量绑定可以更改，这是建立在环境或者构建宏预处理程序指令的时间定义的基础上的。
This is because the actual source code and the variable binding can change, based on the environment or the build time definitions of macros and preprocessor commands.
源文件中的这个点通常由一个词素进行标记，而预处理程序不会使用该词素作为一个语言符号，这表示它并不是一项预处理程序指令。
This point in the source file is usually marked by a lexeme that is not consumed as a token by the preprocessor, meaning one that is not a preprocessor directive.
