Compilation error Win10 MinGW error: 'SM_SYSTEMDOCKED' was not declared in this scope

Describe the bug
Tried to compile on Windows 10 with MinGW64 but got this win32 api related error:

g++.exe -Wall -Wextra -Wpedantic -mwindows -o main.exe .\klog_main.cpp

.\klog_main.cpp: In function 'int Save(int)':
.\klog_main.cpp:142:46: warning: unknown conversion type character 'F' in format [-Wformat=]
142 | strftime(s, sizeof(s), "%FT%X%z", &tm_info);
| ^
.\klog_main.cpp: In function 'bool IsSystemBooting()':
.\klog_main.cpp:204:33: error: 'SM_SYSTEMDOCKED' was not declared in this scope
204 | return GetSystemMetrics(SM_SYSTEMDOCKED) != 0;

Desktop (please complete the following information):

• OS: Windows 10 22H2 build 19045.4651

Additional context
Latest source from master => windows/klog_main.cpp

As a workaround, I replaced the constant with the actual value:

return GetSystemMetrics(0x2004) != 0;

It complies well and works. However would be nice to figure out why the constant is not defined in compile time.
