/* 2.6 tweak:
* In 2.4 there is only one, relative hyst value, (default 10).
* In 2.6 there are two, absolute values.
* The library will link hyst (2.4) to temp_hyst2 (2.6) and we have
* to compute the relative value from temp_hyst2 and temp_crit2.
* We detect that using the following rules:
* - if hyst is not in the range 0..31, it is absolute (2.6);
* - if hyst exceeds tcrit1 or tcrit2, it is absolute (2.6);
* - if hyst is greater than it would be if considered absolute,
* it is absolute (heuristic);
* - else it is relative (2.4).
* Also note that the use of low and high right below is
* arbitrary, only to reuse previously defined variables, at the
* admitted cost of a lower readability.
