1560  * The section names are returned as a list of strings with an extra
1561  * '\0' to mark the end of the list. Except for that the behavior
1562  * depends on the Windows version.
1563  *
1564  * Win95:
1565  * - if the buffer is 0 or 1 character long then it is as if it was of
1566  *   infinite length.
1567  * - otherwise, if the buffer is too small only the section names that fit
1568  *   are returned.
1569  * - note that this means if the buffer was too small to return even just
1570  *   the first section name then a single '\0' will be returned.
1571  * - the return value is the number of characters written in the buffer,
1572  *   except if the buffer was too small in which case len-2 is returned
1573  *
1574  * Win2000:
1575  * - if the buffer is 0, 1 or 2 characters long then it is filled with
1576  *   '\0' and the return value is 0
1577  * - otherwise if the buffer is too small then the first section name that
1578  *   does not fit is truncated so that the string list can be terminated
1579  *   correctly (double '\0')
1580  * - the return value is the number of characters written in the buffer
1581  *   except for the trailing '\0'. If the buffer is too small, then the
1582  *   return value is len-2
1583  * - Win2000 has a bug that triggers when the section names and the
1584  *   trailing '\0' fit exactly in the buffer. In that case the trailing
1585  *   '\0' is missing.
1586  *
1587  * Wine implements the observed Win2000 behavior (except for the bug).
1588  *
1589  * Note that when the buffer is big enough then the return value may be any
1590  * value between 1 and len-1 (or len in Win95), including len-2.
