  It turns out that was merely a problem with a single compiler.
Three out of four compilers said the division was ambiguous.
  But, in the absence of any other fixed point types, Ada accepts
    Long_Float_Functions.Cos(Long_Float(Ada.Numerics.Pi/integer(i)))
and calculates pi/i as type Duration, then converts that to
a Long_Float and then takes the cosine.  That typically means
the argument is not nearly as accurate as the person using
Long_Float would expect, and of course neither is the resulting cos.
