I have been running both ObjectAda and GNAT in paralell and i had found 
that the easiest way to move from ObjectAda to GNAT is the folowing 
approach.

The maybe tricky parts:
   * Get a clear view of the build dependencies in the current system.
   * Get all your source code to match the GNAT naming conventions.

The booring part:
   * Set up a project structure matching the ObjectAda structures with 
GNAT project-files ".gpr" files (no library projects at this point).

The fun part:
   * Build your programs using GNAT.
   * Verify.

The final part:
   * Change the "library" projects to be real library projects (static) 
in  the GNAT environment and do a complete build.
   * Change the desired static libraries to be dynamic.
   * Recompile and copy the DLL:s to the correct directore for execution.
   * Verify.
   * Done.

    I have done this with a >2MSLOC system almost single handed.
