I always found it easier not use a Fortran main program when I was mixing
Ada and Fortran. It is a lot easier if you write a litte Ada main program
which does nothing else but to call a Fortran procedure which is equivalent
to your current Fortran main program. In this Ada main program you should
"with" all Ada packages that you are going to use. In this way you give
Ada a chance to get the elaboration of all your Ada packages right as well.
You can also compile and link then with just one gnatmake call where you
only have to provide the *.o files of your Fortran code in addition to
the normal Ada flags.

Hope that helps

Michael
