* Is calling this "cpp" really the right thing to do.  When we install the unix
  version, won't it overwrite the official Unix cpp?
* Does rodata.c really have to be compiled with -R?  The m68k version isn't
  anyway (?).
* Does someone understand why one needs rodata.c extracted from y.tab.c?
  I just don't know enough about the way yacc ticks (nor do I want to).
* Wouldn't it be nice if cpy.[yc] didn't have to include yylex.c?
* Should we wire the buildfile to put cpy.c, rodata.c in the mi directory
  rather than building copies in each machine directory?
  Same goes for another part of cc68 - ccom, I think.
