the pc address space got bigger in 2005 so that programs could
use more than 2gb of memory.  the top of the stack is now
0xdffff000 instead of 0x7ffff000, so if you s/0x7/0xd/ you
will probably be okay.  it would be even better if _main looked
at its stack pointer and anded off some bits, so that those
weren't hard-coded.

power didn't move, and mips and sparc aren't in the main tree anymore.
