Yep, it still does.

Besides adding the subsystem option, -mwindows does a bit more besides,
adding "-lgdi32 -lcomdlg32" to the link command-line. That's probably not
relevant here though.

It should be used when you want a GUI application rather than a console
application, i.e. one that's going to have a window and pump windows messages.
It's not entirely surprising that you'd get no console when you add it to
the command-line. (If you need both a console - maybe hidden - and a win32
message loop as well, I think you can make a GUI app that calls AllocConsole
