The OS truncates the names to 8+3 limits automatically when the
tarball is untarred; that truncation is an integral part of the
operation of the DOS system calls which work with file names.  So the
only 2 problems that we need to fix with entries in fnchange.lst are:

  - When 2 or more files produce the same name after truncation to
    8+3;

  - When a file's name includes characters that are disallowed in DOS
    file names.  Examples of such characters include `+', `,', `:',
    and a few more.  File names with leading dots, like .gdbinit, are
    also not allowed.

The fnchange.lst file is submitted to a program used to untar the
distribution (see djunpack.bat for the gory details), and which
performs the renaming on the fly.  That program automatically renames
some of the files whose names are invalid on DOS and are frequently
used in GNU software, like foo.c++, .foobar, etc.  This is another
reason that some invalid names might be missing from fnchange.lst.
