FWIW: $ x86_64-w64-mingw32-gcc -print-sysroot /usr/x86_64-w64-mingw32/sys-root which would indicate that you are correct that /mingw is somehow "inside" the sysroot. However I have no idea about what the correct sysroot should be, just that what we have now works and changing it would be a massive PITA so I wouldn't want us to do it without very good reasons.
