	* sem_ch12.adb (Analyze_Generic_Package_Declaration): If there
	is a default storage pool, add a corresponding aspect to the
	generic unit, to be used at the point of instantiation.
	(Analyze_Package_Instantiation): If generic unit has aspect
	specifications, propagate them to instance. If instance has a
	Default_Storage_Pool aspect, make sure that it overrides the
	one that may be inherited from the generic.

	* prj-attr.adb: Minor removal of attributes of package Linker
	that have never been used and never been documented.
	* projects.texi: Add documentation for attribute Runtime.
	* prj-nmsc.adb (Check_Configuration): Do not report a warning
	for unknown compilers when the project is externally built.
