        * decDouble.h (decDouble): Replace struct with union accessible
        by more types.
        * decSingle.h (decSingle): Ditto.
        * decQuad.h (decQuad): Ditto.
        * decNumberLocal.h (DFWORD, DFBYTE, DFWWORD): access decFloat via
        new members.
        * decBasic.c (decFloatCompareTotal): Avoid type-pun violation.
        (decNumberCompare): Ditto.
