There should be done two fixes: first, remove "-gnatg" from Makefiles.
Second, search and replace "GNATCOM.Interface" to "GNATCOM.COM_Interface"

IIRC it was enough.



There is one problem, however: Win32API is indeniably harded to use in 
Ada compared to using WinAPI in Delphi, the same goes to GNATCOM. I have 
impression that the one who designed these binding generator have 
primarily used C++ (not counting Ada) and didn't have experience working 
with Delphi. As a consequence, GNATCOM is as hard to use as it is to use 
COM in C++.

At least, GNATCOM exists.
