    DEFCONSTANT is defined in the manual to produce values that are EQUALP
    only.  Not EQ.

Not so.  I assume you are referring to page 49 of the Laser edition.  It
says nothing about any relation between the values of different instances
of open-coding of the variable by the compiler.  What it does say is that
if you evaluate the form (DEFCONSTANT var val) twice, it is an error unless
the two values of val are EQUALP.  But this misfeature has already been
removed by a previous ballot.
