Looking at the sources I see that your original AD was written for 
MS-DOS, and that AdaGide contains a modified version for WinNT. But even 
the adapted sources have not been updated since 1999.

Yes, this is an interesting alternative.

I've put the message reporting code in a separate subroutine, called 
from the exception part of the main procedure.

Your post has alerted me about a new version of AdaGide. I was using 
v7.0, thas has a different set of options. After installing v7.3 I see a 
checkbox that enables/disables the usage of AD.

Thanks, a lot.
