The problem here is the "test_boundary" funciton.  In this function I check to 
see the REAL number given is valid for the floating point format selected.
To do this, I need to use the math_real function "**".  Altera just doesn't like 
this funciton.

1) Call this into Altera as a bug.

2) Work around (pretending that denormal, and infinite numbers don't exist):

   function test_boundary (
     arg                     : REAL;     -- Input, converted to real
     constant fraction_width : NATURAL;  -- length of FP output fraction
     constant exponent_width : NATURAL;  -- length of FP exponent
     constant denormalize    : BOOLEAN := true)  -- Use IEEE extended FP
     return boundary_type is
   begin  -- function test_boundary
     if arg = 0.0 then
       return zero;
     else
       return normal;
     end if;
   end function test_boundary;
