In mopers.lisp MUL* and MUL are given compiler-macro definitions via
DEFOPT. In particular, if we have exactly two arguments, MUL* is
transformed to the broken MUL2* from opers.lisp. In 5.9.0 DEFOPT
itself had a bogus definition and did nothing (see defopt.lisp), so
for MUL* the definition in runtim.lisp was used.
