GNAT compilers for the Alpha fully implement the DEC
pragmas (Float_Representation, Long_Float) which provide
fine control of the kind you are looking for. The default
is IEEE, which is of course usually preferable, but
Vax_Float is supported particularly for compatibility with
existing legacy code and data files.
