This is usually the problem when calling from C, but from C++ the real
problem is that you must provide

	-acpp -prototypes

as flags to CC (which then passes them on to cc).

There are some ramifications once you start doing this, which you must do
for all C++ programs. I have found that iostream operators break with
floats; you must cast them to double like this:

	float aFloatVar = 1.0e0;
	cout << (double) aFloatVar;

I believe that you must recompile the libraries when you have provided
these flags.
