/* The my_ansipath() function takes a Unicode filename and converts it

*
* The buffer to the ansi pathname must be freed with Safefree() when it
* it no longer needed.
*
* The argument to my_ansipath() must exist before this function is
* called; otherwise there is no way to determine the short path name.
*
* Ideas for future refinement:
* - Only convert those segments of the path that are not in the current
* codepage, but leave the other segments in their long form.
* - If the resulting name is longer than MAX_PATH, start converting
* additional path segments into short names until the full name
* is shorter than MAX_PATH. Shorten the filename part last!
