If you try to use gcc 3.4.x, you can use libwin32ada.a from gnatwin-3.15p.exe copy this file to C:\Mingw\lib directory With this file, and standard object files from Windows, you should compile and link all win32.xx sources from gnatwin Note this doesn't work with Gnat 3.15p which is poorly compatible with Microsoft object files.
