*
* Win2000:
* - if the buffer is 0, 1 or 2 characters long then it is filled with
* '\0' and the return value is 0
* - otherwise if the buffer is too small then the first section name that
* does not fit is truncated so that the string list can be terminated

* - Win2000 has a bug that triggers when the section names and the
