Compilation Issue with VS 2022

ArmorPaint version: Latest commit hash is: d9dbdb6

OS/device including version: RX 6750 XT

Issue description: Followed the official build instructions, seeing the following build errors in iron_array.h

1>C:\projects\armortools\armorcore\Sources\iron\iron_array.h(53,24): error C2016: C requires that a struct or union have at least one member
1>(compiling source file '../../armorcore/Sources/iron/iron_array.c')
1>C:\projects\armortools\armorcore\Sources\iron\iron_array.h(54,29): error C2016: C requires that a struct or union have at least one member
1>(compiling source file '../../armorcore/Sources/iron/iron_array.c')

Seems like the C standard doesn't allow for empty structs, which is how they are declared:

typedef struct buffer {} buffer_t;
typedef struct buffer_view {} buffer_view_t;

I've tried switching the C standard (defaults to Legacy MSVC) to C11 and C17 by configuring the project settings in VS2022 but no success. I believe the empty structs are allowed in C++ but not C, and I think this file is being compiled by the Visual C compiler rather than the C++ compiler.

Ran the following prior to opening the solution in VS, had no issues with this:

C:\projects\armortools\armorpaint>..\armorcore\Kinc\make --from ..\armorcore -g direct3d11

Should be resolved, thanks for report.

TY so much for the patch and for pushing this industry forward.

Fantastic. Thank you. But... did a git fetch followed by git merge origin/main

and then in Visual studio.. Build| Build Solution... still same error Severity Code Description Project File Line Suppression State Details Error C2016 C requires that a struct or union have at least one member ArmorLab D:\Studio Work v2\Mirror\armorlab\armortools\armorcore\Sources\iron\iron_array.h 53
Severity Code Description Project File Line Suppression State Details Error C2016 C requires that a struct or union have at least one member ArmorLab D:\Studio Work v2\Mirror\armorlab\armortools\armorcore\Sources\iron\iron_array.h 54

typedef struct buffer {} buffer_t; typedef struct buffer_view {} buffer_view_t;

Am I doing something wrong? I am a newbie to GIT so very probable... please help
