However, if you assume a specific compiler and a specific system, it may be doable, and fortunately, with GCC on Linux, it is.
不过，如果假定有一个特定编译器和一个特定系统，那么可能可以这样做，幸运的是，对于Linux上的GCC，恰好是这种情况。
For some of the utilities like is_enum, there is no easy way to do this, and the implementation has to depend on specific compiler sources to achieve the desired result.
对于is_enum等一些实用程序，没有实现此目标的轻松方法，必须依赖于具体的编译器来源来实现想要的结果。
