Subject: add translations for new sections that are mmapped or when the brk is
 changed Add a default machine width parameter Arch based live processes

    Add a default machine width parameter
mem/port.hh:
    gcc 4 really wants  a virtual destructor
sim/byteswap.hh:
    remove the comment around long and unsigned long even though uint32_t
    and int32_t are defined. Seems to work with gcc 4 and 3.4.3.
sim/syscall_emul.cc:
sim/syscall_emul.hh:
    add translations for new sections that are mmapped or when the brk
    is changed
