Confirmed, reduced a lot:
int zip_find_end_of_central_dir(void *in, long long *len)
{
    char buf[256];
    int i = 0;
    long long filelen;
    long long filepos;
    int  maxread;
    int totalread = 0;
    int found = 0;
    unsigned extra = 0;
    filelen = __PHYSFS_platformFileLength(in);
    filepos = 0;
    maxread = (unsigned) filelen;
    while ((totalread < filelen) && (totalread < 65557))
    {
        extra = *((unsigned *) (&buf[0]));
        for (i = maxread - 4; i > 0; i--)
        {
            if ((buf[i + 0] == 0x50) &&
                (buf[i + 1] == 0x4B) &&
                (buf[i + 3] == 0x06) )
            {
                found = 1;
                break;
            }
        }
    }
    return (!found) ;
}
