 *                         constdecs.h
 *  This file declares the routines which detect constant expressions and
 *  extract them from loops.
 *
 *  The type maxconst returns information about the expression under
 *  consideration. The field self is true if the expression as a whole is
 *  constant within the program fragment under consideration. If the
 *  entire expression is not constant (self is false) then the field cont
 *  is a list of the sub-expressions which are constant within the
 *  specified region.
 *
 *  The type maxconst is defined in consttypes.h
 *
 *  The principal procedures declared here are mc_list and repeat_const.
 *  They are decribed in const.c
