It varies.  In some, it is the sum of the space given to the
primary and secondary stack, which "grow" toward each other.
In others, it only controls the primary stack, and the secondary
stack is represented as an arbitrarily extendable linked-list of
large chunks.  There are probably other combinations as well.

I would guess that many compilers that run on Unix-like timesharing
systems use the automatic stack extension feature to handle the
main primary stack, and either have a fixed size for the secondary
stack, or represent the secondary stack using chunks and have no
fixed limit.  On most embedded systems, I suspect that the main
task's primary and secondary stack sizes are set at link-time.
