Jordan K. Hubbard b2d228d3d7 This will now compile and even scribble helpfully on your disks.
It remains to be seen how successfully.  The distribution loading code
is still not here yet, but the partition/newfs/mount/cpio-extract cycle
is as complete as it's ever going to get, modulo possible bug fixes.
The TCP/IP setup screen is also sort of here, albeit in a highly-changing
state due to the fact that per-interface information isn't being kept
right now but is being added (thanks, Gary!).
