The problem is that Ada and C++ both have the notion of "stuff that has
to happen before the main program". The Ada 95 standard makes this
easier by defining a linker symbol "adainit", which is a procedure that
encapsulates all that "stuff" from the Ada side. See B.1(39) of the Ada
95 Reference Manual. There's also an interface for the finalization
side of things (Ada and C++ both have finalization).
If you use GNAT (the GNU Ada compiler), there is a more straightforward
interface to C++, with no need to go through C. Ada has dispatching
functions that can interface directly to C++ virtual functions.
