Why does the following code work on every other c compiler in the world,
that I've used, and not manx 3.6a?

/*
        initial image maker
*/
# include <stdio.h>

# define newInteger(x) ( (intobj = x)<0 ? intobj : (intobj<<1)+1 )

typedef short object;

main(argc, argv)
int argc;
char **argv;
{
        object intobj,x;

        x = newInteger(8);
}

p.s.
    You wouldn't think that the compiler would generate illegal code.
    It seems to me to be a strange place to fail.
