I believe the latter is correct (except that no 
SS change should be needed), at least this is how 
it works for other targets as far as I know. 
Amount of memory to be allocated for stack is 
passed as a parameter during thread creation.

BTW, in case you manage to create thread manager 
(systhrd.inc implementation) for GO32v2 target 
and are willing to share it with others, we'd be 
certainly interested to add it to FPC.
