Don't do this.  First, SCM_VCELL and SCM_VARIABLE are not the same
thing.  You can't substitute one for the other.  (Likewise for the
substitutions.)  Second, we already keep proper backward compatibility
in the C code itself:

    #if (SCM_DEBUG_DEPRECATED == 0)

    #define SCM_CONST_LONG(c_name, scheme_name,value) \
    SCM_VCELL_INIT(c_name, scheme_name, scm_long2num(value))

etc...
