Yes, but off the top of my head I cannot think of a great way to check
that DTYPE has backup code for systems that do not have d_type.

At least in the case of 'git diff --no-index' the tests will fail if we
do not properly detect a file is a directory. So at least we will likely
know upon running 'make test'. Still that requires manual investigation,
so not perfect, though...

I assumed that it was a hard dependency and could not be disabled. Am I
wrong?

Anyways, it was quick so no worries. I posted my findings [1].
