I thought I already said it... it isn't exported from dinput, it comes
from the static library that goes with it (which is more than just a mere
import library, it also contains pre-initialized convenience variables
such as these).

No Windows applications use it, since the variable's contents is linked in
statically... which incidentally also makes the Winelib implementation
much easier to do than you propose.
