makegpr.adb (Compile_Link_With_Gnatmake): Invoke gnatmake with -d if gprmake was invoked with -d.

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

	* makegpr.adb (Compile_Link_With_Gnatmake): Invoke gnatmake with -d if
	gprmake was invoked with -d.
	(Compile_Sources): If -d was used, output the "completed ..." message
	for each compilation.
	(Scan_Arg): Recognize new switch -d
	When -c and at least one main is specified, set
	Unique_Compile to True to guarantee that no other sources will be
	compiled.
