The standard says too little about the preprocessor. I don't think you can implement a preprocessor that can read system header files only with the standard.

- eliben 11y agoSystem header files usually employ platform-specific extensions not only on the preprocessor side, but in preprocessed code as well AFAIK. That is, the compiler has to support them too. My comment was not to say that coding cpp is easy - just that it's not a particularly hard task compared to the compiler itself.
