--- Comment #4 from Marc Adams <madams846 at hotmail dot com> ---
A simpler report would have been "printf fails for decimal constant".
Statement printf(" %Df ",2.0dd) produces output "%Df" on my system. That
basic statement should work on any system. It should be "needed" because it
produces output and it should work without extra compiler switches. Thanks for
your attention.
