Subject: Minimal pragma Export (StdCall... example?

Hi all, 

I'm trying to write a DLL using GNAT 3.15p on Windows XP.  The DLL needs to 
export functions with the StdCall calling convention so that they can be 
called from Visual Basic.  Using samples/dll/ from the gwindows distribution 
as a starting point, I haven't been successful in getting this to work.  

If I just change the occurrences of pragma Export (C... to pragma Export 
(StdCall..., the Ada test driver program call_gw_dll.adb fails to link because 
the link library libgw_in_a_dll.a exports "_pop_a_window" only, while the 
linker wants "pop_a_window@0".  Neither of these is the "_pop_a_window@0" I 
would have expected to see for a StdCall function.  

Does anybody have a minimal set of code for a DLL, test program, and makefile 
that demonstrates building a StdCall DLL using GNAT on Windows?  

Best regards, 
John
