Description
The current macro translation solution has many defects, such as being unable to translate a simple integer type conversion. Therefore, I implemented a macro translation solution based on lang-c using recursive transformation. A simple hack implementation is here (non-invasive to bindgen, because modifying the bindgen library seems like a big project):

This is an example of my use of it:
https://github.com/823984418/hc32_driver_sys
I think this is a great idea, so I’m sharing it here. The implementation is still rough, but it simply expresses what I want to achieve.

Research direction
Start by reading the linked lang-c hack_bindgen.rs implementation and the hc32_driver_sys usage example, then compare their recursive AST transformation with bindgen's current macro translation. The issue does not name bindgen files or tests and defines no acceptance criteria, so the intended scope and validation for a complete change would need to be established first.
