Dear VTK Users and Developers.
Recently, I encountered a problem in compiling VTK 9.2.2 source code with GCC 12. But before that, I encountered a [problem](https://discourse.vtk.org/t/vtk-9-1-mingw64-and-windows-10/7116) that has been solved.
When the source code is compiled to 79%, the following problem occurs:
The following are similar errors until the compilation is interrupted:
My environment is as follows
- OS: Windows 11
- Kits:
- CMake 3.25.1
- GCC ([x86\_64-12.2.0-release-posix-seh-ucrt-rt\_v10-rev2.7z](https://github.com/niXman/mingw-builds-binaries/releases/download/12.2.0-rt_v10-rev2/x86_64-12.2.0-release-posix-seh-ucrt-rt_v10-rev2.7z))
When I use CMake to generate **makefile** files, I only set the **CMAKE\_BUILD\_TYPE**
to **Release**

`STRICT` is a macro coming from…somewhere, probably a Windows header. I think we fixed this recently for Windows directly, but I suppose it needs tweaks for MinGW as well.

No solution, I recommend using version 9.1.0 first

My dear friend, the source code of the latest version (master: 68f2a087b3e3daa) has just been compiled. This [issue](https://discourse.vtk.org/t/vtk-9-1-mingw64-and-windows-10/7116) still exists.
