Well, it is very controversial thing, for one. The trouble is, that even
gcc can not really guarantee it, since initial stack assumptions are not
controlled by the compiler, but rather by the combination of an OS
and how linking was done.
We've discussed adding this feature to Sun Studio, but still I don't
know of portable and reliable way of doing it. Hence the current
state of affairs.
