... Definition 2: "c:" / x / "c:" = "c:" / x "a:" / x / "c:" = "c:" for a != c and no element of x is a drive. This is similar to what SetCurrentDirectory does, and implies that c:a/b isn't absolute.

Actually the problem of this definition is that it cannot be associative given the current Windows path syntax.

To support c:a, we need either to distinguish between "c:" and "c:/" as path elements, or posit that c:/ consists of { "c:", "/" }. The openat-based definition then becomes associative (using either), if I'm not mistaken. Although I very well could be, because did I mention the word madness in relation to all this? I forget.
