ezunits fundamental_units apparently broken in Maxima 5.49.0

Dear Maxima List Readers,

with latest Maxima the ezunits fundamental_units function doesn't work 
as expected any more - it did work last time I tried it (which is a 
longer while back - maybe 2 years). I am using ezunits very frequently 
but only rarely in situations which need manual simplification using 
fundamental_units.

I get:

(%i1)    load(ezunits)$

(%i2)    fundamental_units(1`N);
(%o2)    (kg*m)/s^2

(%i3)    fundamental_units(1`J)
(%o3)    fundamental_units(1 ` J)

(%i4)    fundamental_units(1`Pa);
(%o4)    kg/(m*s^2)

(%i5)    fundamental_units(1`W);
(%o5)    fundamental_units(1 ` W)

(%i6)    fundamental_units(1`V);
(%o6)    fundamental_units(1 ` V)

(%i7)    fundamental_units(1`Ohm);
(%o7)    fundamental_units(1 ` Ohm)

(%i8)    1`N*m``J;
(%o8)    1 ` J

For many units it just returns a noun form - but it apparently knows the 
units. Am I missing something?

Best regards,

Michael
