Thanks for taking care of these, yet I wonder how I would have
noticed. Besides the -mingw32 and -mingw64 (cross) testing that
I had already done on 32-bit and 64-bit Linux respectively, I've
just now done a x86_64-w64-mingw32 (cross) run without it
triggering any test failures. I therefore suspect there are more
build options that are needed to expose these failures?
