Robert Dewar (dewar@merv.cs.nyu.edu) wrote about the C++ interfacing pragmas:

: But you really have to know what you are doing to use them. Generally they
: are intended for use by a binding generator, not by humans.

In the GNAT Reference Manual there are references to "the C++ binding
generator tool". Where can I find/buy that tool?

: The easiest thing for most people is to write a C wrapper for their C++
: code and to interface to the C wrapper. This can be done using only
: standard features of the language as described in annex B of the RM.

This seems a bit silly if you want to extend a C++ class in Ada. - Is this
suggestion just intended for old fashioned procedural code, or can you
explain how you would do it with a C++ class?
