Inconsistent directory structure Help!!

The issue tracker is **ONLY** used for the CPP/C client (feature request of RocketMQ need to follow [RIP process](https://github.com/apache/rocketmq/wiki/RocketMQ-Improvement-Proposal)). Keep in mind, please check whether there is an existing same report before your raise a new one.

Alternately (especially if your communication is not a bug report), you can send mail to our [mailing lists](http://rocketmq.apache.org/about/contact/). We welcome any friendly suggestions, bug fixes, collaboration, and other improvements.

Please ensure that your bug report is clear and that it is complete. Otherwise, we may be unable to understand it or to reproduce it, either of which would prevent us from fixing the bug. We strongly recommend the report(bug report or feature request) could include some hints as to the following:

**BUG REPORT**

1. Please describe the issue you observed:

- What did you do (The steps to reproduce)?
i used `re_dev` branch

- What did you expect to see?
The `master` branch and the `re_dev` branch have the same directory structure

- What did you see instead?
`re_dev` include directory include/c and include/*
`master` include directory include/*

比較 master 和 re_dev 分支上的 include/ 目錄，尤其是 include/c 以及報告中提到的其他 include 項目。檢查分支歷史或儲存庫指引，以確定預期採用哪種結構；當兩個分支具有約定的目錄配置時，即表示完成。
