I completly agree with Robert here.

I have been able to build DLL with GNAT 3.09, 3.10 and 3.11.

Each time it is getting a bit simpler though and GNAT handles more
DLL specific stuff.

Anyway this is not GNAT specific at all. GNAT is based on GCC and it
has been possible to build DLLs with CYGNUS GCC since a long time.

So I'm pretty sure that it was also possible to build DLL with earlier
version of GNAT, but I've never done that.
