gc_inhibit_torture definition twice?

I have a problem to understand the way gc_inhibit_torture is defined.

In include/Defn.h it is declared as extern, using the __MAIN__ trick this leads to
a definition in main/main.c.

But in main/memory.c you define (and initialize) gc_inhibit_torture again:

    int gc_inhibit_torture = 1; /* gets set to zero after initialisations */

Then, in e.g. unix/system.c immediately at the beginning of main() you initialize 
gc_inhibit_torture once more:

int main(int ac, char **av)
    int value, ierr;
    char *p, msg[1024];
    structRstart rstart;
    Rstart Rp = &rstart;

    gc_inhibit_torture = 1;
Can anybody explain the reason for this implementation?
