(discard_tty_input) [MSDOS]: Do it by reading till no more keys available.
(init_baud_rate) [MSDOS]: Assume highest possible speed.
(sys_suspend) [MSDOS]: Save default directory. Call via system, not via fork.
(emacs_get_tty, emacs_set_tty) [MSDOS]: Don't do anything.

expand_and_dir_to_file) [MSDOS]: Drive letter support.
(Fexpand_file_name) [MSDOS]: Support for multiple default directories.
(Ffile_writeable_p) [MSDOS]: Don't call access with file name ending in slash.
(Finsert_file_contents) [MSDOS]: Determine file type by name (call
find-buffer-file-type) and change CR+LF to LF if it is a text file.
