When I was compiling tbb(https://github.com/oneapi-src/oneTBB), I encountered
the following issues:

I found that the file issue occurred in
G:\x86_64-w64-mingw32\lib\gcc\x86_64-w64-mingw32\14.0.0\include\waitpkgintrin.h
, line 52. When I removed the attribute __always_inline__, the compilation was
successful.
