	* makegpr.adb (Build_Global_Archive): Make sure the list of sources is
	correctly computed and the main project data is not modified while
	doing so.
	(Add_C_Plus_Plus_Link_For_Gnatmake): Always link with the C++ compiler
	(Choose_C_Plus_Plus_Link_Process): Do not generate shell script
	c++linker as this does not work on some platforms.
