Ada 95 compilers are encouraged to provide support for
the "main" routine being written in something other than
Ada.  This could presumably help with your problem.  Note
that similar problems will occur in any language with a 
non-trivial RTS (e.g. C++, Lisp, Smalltalk, even Fortran in some
implementations).  

In any case, this is a very reasonable thing to request of
your implementor, and they might already have a solution.
Probably you should check with them.

Alternatively, give GNAT a try.  It uses the standard C runtime
routines as much as possible, presumably minimizing the problem.
