At least the w32 version of accept-process-output was broken in the
past, see the comment in tramp-accept-process-output. But this was Emacs
22 time, so hopefully it is fixed now.

I would need to test with Emacs 24, whether this is fixed. No chance for
*me*; I'm lucky when I can test with a recent Emacs on a w32 system.

Well ... I'll test with Emacs 26, and if it passes the tests, I'll
assume it works also with Emacs 24 and 25.
