The current numeric class doesn' work with GCL.  It seems that GCL is
missing the REAL class.  It has the REAL type, but not the REAL class. 
I don't know why.  It would be best if we could somehow tell GCL about
the REAL class, but I don't know how to do that.  I'll have to change
all the methods specialized on REAL to specialize on FLOAT and add an
equivalent method for RATIONAL.
