>Description:
	
	The following patches are needed to run a coda client on mac68k
	[developed with help from Bill Studenmund]. 

	With these, I was able to serve a coda filesystem to a client
	on the same machine, a Quadra 840AV, client and server built 
	using the anoncvs'd current coda sources. The results were less
	than stellar--"ctoken" causes the machine to grind to a halt.
	That could well be a bug in the client or server, and is no
	reason to leave the CODA filesystem disabled.

	I chose a major number of "44" simply because it's the next
	available. The "vice-setup" script makes a /dev/coda with a major
	number of 60, but that's easy to fix once a number is settled on.
