This is the simple calculator rewritten on Linux using the current
rpcgen.

mc.x is as it used to be.
	% rpcgen -a mc.x
generates all the files we need including templates 
for the client and the server.

I modified the Makefile.mc file produced by rpcgen by just renaming it Makefile.

I modified the mc_client.c file to insert a trivial user interface.

I modified the mc_svc.c file to insert the code to do the addition and subtraction.

Then I did 
	% make
and the client and server where there and usable:
	% mc_server &
	% mc_client localhost
