AnimModel.cpp reaches cParser through the simulation core, not a direct import, so the previous pass missed it; the propagation now follows the whole import closure. Train.cpp, drivermode.cpp and Globals.cpp call Console:: inside _WIN32 guards without importing eu07.console - invisible on Linux, where those blocks are skipped.
