+ modify version-check with Ada generics to use the same pattern as in the check for supported gnat versions (report by Pascal Pignard). > additional changes for building with Visual Studio C++ and msys2 (patches by "Maarten Anonymous"): + adjust headers/declarations to provide for "dllimport" vs "dllexport" declarations when constructing DLLs, to worko with Visual Studio C++.
