Piotr Caban (@piotr) commented about dlls/msvcrt/mbcs.c:
#include <stdio.h> #include <limits.h> +#include <locale.h>
The patch is marked as draft so I'm not sure if you consider it ready. It generally looks good for me. The CI test job sometimes fails - you can ignore the failure since it's not related to your patch.
Please change the commit message to something like: ``` msvcrt: Add _mbctolower_l partial implementation.
Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=45273 ```
locale.h include should not be needed.
