Fix compiler warning on Windows (GH-18012)

2020-01-15T17:07:09+00:00

Python-ast.h contains a macro named Yield that conflicts with the Yield macro
in Windows system headers. While Python-ast.h has an "undef Yield" directive
to prevent this, it means that Python-ast.h must be included before Windows
header files or we run into a re-declaration warning. In commit c96be811fa7d
an include for pycore_pystate.h was added which indirectly includes Windows
header files. In this commit we re-order the includes to fix this warning.

bpo-37500: Make sure dead code does not generate bytecode but also detect syntax errors (GH-14612)

Add a new field to the compiler structure that allows to be configured

walking the nodes while preserving optimizations.
