We have a package with db-related stuff for each table we have in our 
system - which is about 300. These are auto-generated from xml.

In order to get away from our home brew linked list,
I added a list of type Add.Containers.Doubly_Linked_List.
and for make something else easier we added a hashmap as well.

Now that made the exesize grow so big, that we had to patch ld on AIX
to use more that 1Gb mem...

The resulting exe went from 200 to 280 mb...

Some exefiles were still too big, so at auto-generation these features are
only inserted if the table in question is configured to do so.

Yes, generics is voluminous with gnat.
