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.

--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
This is a user error.
The _tpause intrinsic requires the caller to be compiled with -mwaitpkg, which
given the above error didn't happen.

Note the improved diagnostic for the error message is PR 90798 (and PR 82094).
