        !             2:  *      svr3z.ifile - for collectless G++ on i386 System V.
        !             3:  *     Leaves memory unconfigured at address 0.

        !             7:  *     BLOCK to an offset that leaves room for many headers ( the value
        !             8:  *     here allows for a file header, an outheader, and up to 11 section 
        !             9:  *     headers on most systems.
        !            10:  *     BIND to an address that excludes page 0 from being mapped. The value
        !            11:  *     used for BLOCK should be or'd into this value. Here I'm setting BLOCK
        !            12:  *     to 0x200 and BIND to ( 0x400000 | value_used_for(BLOCK) )
        !            13:  *     If you are using shared libraries, watch that you don't overlap the
        !            14:  *     address ranges assigned for shared libs.
        !            15:  *
        !            16:  *     GROUP BIND to a location in the next segment.  Here, the only value
        !            17:  *     that you should change (I think) is that within NEXT, which I've set
        !            18:  *     to my hardware segment size. You can always use a larger size, but not
        !            19:  *     a smaller one.
