A standard MinGW installation has its headers in /mingw/include.
I'm guessing you've got a foreign stdio.h in /usr/include, and by
overriding the default header, (your -I... path is searched first,
so the search stops at the incompatible stdio.h there), you've
generated a bad reference -- in this case it's an improper
declaration for the `FILE stderr' reference.
