/* MS-DOS and similar non-Posix systems have some peculiarities:
- they distinguish between binary and text files;
- they use both `/' and `\\' as directory separator in file names;
- they can have a drive letter X: prepended to a file name;
- they have a separate root directory on each drive;
- their filesystems are case-insensitive;
- directories in environment variables (like INFOPATH) are separated
by `;' rather than `:';
- text files can have their lines ended either with \n or with \r\n pairs;
These are all parameterized here except the last, which is
handled by the source code as appropriate (mostly, in info/). */
