Please look again into my mail :)

 ptr = mmap(0, nbp*BIGSZ, PROT_READ|PROT_WRITE, MAP_SHARED, fd, 0) ;
        if (ptr == (char *)-1)
                ptr = mmap(0, nbp*BIGSZ, PROT_READ|PROT_WRITE, MAP_PRIVATE,
fd, 0);

mmap2(NULL, 4194304, PROT_READ|PROT_WRITE, MAP_SHARED, 3, 0) = -1 EINVAL

mmap2(NULL, 4194304, PROT_READ|PROT_WRITE, MAP_PRIVATE, 3, 0) = -1 EINVAL

I tried the two versions. MAP_SHARED and MAP_PRIVATE
