2005-06-14  Vincent Celier  <celier@adacore.com>

	* prj-nmsc.adb (Suffix_For): Change default suffix for C++ to ".cpp"
	(Check_Stand_Alone_Library): If the specified reference symbol file does
	not exist, only issue a warning when the symbol policy is not
	Controlled. And, when symbol policy is Compliant, set the symbol
	policy to Autonomous.
