Hi!
I have a application that explicitly loads other Ada-Dll's (built as
relocatables with GPR files and gprbuild) in GNAT 6.5.0.
When I try to load the same Dll the second time, Ada Elab generates
exception "Program Error" with message "duplicated external tag"!
I have tried to move all "tagged" types away from the visible/exported
side of the Dll's, so it just have the entry points needed. I use
a .def file to limit the visible entry points.
And these entry points are only 5 procedures/functions!
So here's the question!
Is there any way to supress the elaboration checks on "tagged" types,
so that I can load as many Dll's as needed?
Or can this be done in anyother way?

/Thanks
