gdb-inferior-io--init-proc silently punts when it cannot get a useful
name from process-tty-name. It always did that. This initialization
is done during initialization of the session, where displaying error
messages is tricky at best, and I also don't know what message to
display, TBH. But patches are welcome.

Yes: Emacs on Windows uses pipes to communicate with subprocesses,
because PTYs don't exist or cannot be used by Emacs. So there's no
name of a TTY to use in the "set inferior-tty" command.
