Problem solved.  These two errors were caused by an incorrect makefile as
well as incorrect code.  In my %CPU%.h file I had declared write_stacks as
%CPU%::write_stacks write_stacks.  Instead I needed to declare two separate
stacks, %ISA1%::write_stacks write_stacks1 and %ISA2%::write_stacks
write_stacks2.  I also discovered that I had not told CGEN to generate the
files %CPU%-%ISAX%-defs.h.  This caused me to get an incomplete definition
error when I tried to make the altered code.  I fixed this by going into the
makefile in src/sid/component/cgen-cpu/%CPU% and altering it such that it
would cause CGEN to generate the defs files, using the sh and mt ports as
examples.
