   Description:
      Implements the various statements and such like.

/* As of 0.5.4, any statement that calls on ffecom to transform an
   expression might need to be wrapped in ffecom_push_calltemps ()
   and ffecom_pop_calltemps () as are some other cases.  That is
   the case when the transformation might involve generation of
   a temporary that must be auto-popped, the specific case being
   when a COMPLEX operation requiring a call to libf2c being
   generated, whereby a temp is needed to hold the result since
   libf2c doesn't return COMPLEX results directly.  Cases where it
   is known that ffecom_expr () won't need to do this, such as
   the CALL statement (where it's the transformation of the
   call expr itself that does the wrapping), don't need to bother
   with this wrapping.  Forgetting to do the wrapping currently
   means a crash at an assertion when the wrapping would be helpful
   to keep temporaries from being wasted -- see ffecom_push_tempvar.  */
