I'm guessing that the "source" you are working on has been obtained by
unzipping the windows binary zip file. Despite appearances, that is
not the source code. For the proper source code, download the file
that's marked as source. In this case,


clearly labels the following as "Source" (and the corresponding zip
file as "Windows Binary")


This likely answers your other question as well.
