Back on this! It turn out that this breaks the shared Ada runtime. Indeed, exported variables on Ada packages in a DLLs are only accessible when linking against DLL (thanks to runtime pseudo reloc).
With the patch applied it is not possible to build any Ada application using the shared runtime. This is a very serious problem, the patch should be reverted. Sorry for not having remembered before about this and why linking against DLL was so important! -- Pascal Obry -- gpg --keyserver keys.gnupg.net --recv-key F949BD3B
