> (setq etags-regen-program "C:/green/emacs/emacs-29.3/bin/etags.exe")
> (require 'etags-regen)

> 2. Open test.c with the following code

> #define APPLICATION_WINDOW_WIDTH 320
> ```
> 
> 3. M-x etags-regen-mode

> 5. M-x kill-buffer TAGS

> 6. Add `#define APPLICATION_WINDOW_HEIGHT 320` to test.c and M-x save-buffer

> 
> The actual behavior: The echo area reports: "No definition found for: APPLICATION_WINDOW_HEIGHT"

Thanks.
