In fact, pardon me for posting this.  (Our rn isn't retracting postings
properly, sorry.)  The example posted *does* work correctly.  It was an
attempt to determine exactly what the problem was with an application I am
writing.

I have now nailed down the problem.  I'm not sure I would characterize it as
a bug, but I would characterize it as a deficiency.

What was happening was that my prototype, which included some float
declarations, was accidentally followed by an old-style declaration with
no parameter list.

Apparently the second, old-style declaration superseded the new-style
declaration, causing the automatic coercion of floats to doubles.  This
occurred *without* any warning or comment from the compiler.

Sorry, again, for the wasted bandwidth.
