how much stack space can I use

SEMMSL and SEMOPM are limited by stack space:

sys_semctl() needs sizeof(short)*SEMMSL bytes
(up to 1 Kb)

sys_semop() needs 6*SEMOPM bytes.
(up to 600 bytes)

How much stack space can I use without causing a stack overflow? None of
these functions are recursive, and they don't call any subfunctions
which need more than a few bytes stack space.

Is alloca(3) possible/allowed?
