Fixing this super annoying Yield warning was one of my motivation for moving Python-ast.h to the internal C API (pycore_ast.h) :-D I disliked that Python-ast.h defined tons of symbols without "Py" (or "_Py") prefix:

bpo-43244: Remove ast.h, asdl.h, Python-ast.h headers (GH-24933)
These functions were undocumented and excluded from the limited C
API.
Most names defined by these header files were not prefixed by "Py"
and so could create names conflicts. For example, Python-ast.h
defined a "Yield" macro which was conflict with the "Yield" name used
by the Windows <winbase.h> header.
Use the Python ast module instead.
* Move Include/asdl.h to Include/internal/pycore_asdl.h.
* Move Include/Python-ast.h to Include/internal/pycore_ast.h.
* Remove ast.h header file.
* pycore_symtable.h no longer includes Python-ast.h.
