exp_dist.adb (Build_General_Calling_Stubs): New formal parameter RACW_Type, used...

2004-10-26  Thomas Quinot  <quinot@act-europe.fr>

	* exp_dist.adb (Build_General_Calling_Stubs): New formal parameter
	RACW_Type, used in the PolyORB version.
	Rename RCI_Info to RCI_Locator, for consistency between the PolyORB
	version and the GARLIC version.

	* snames.ads, snames.adb, s-parint.ads, s-parint.adb:
	Rename RCI_Info to RCI_Locator for better consistency between the
	GARLIC and PolyORB versions of the distributed systems annex.
	(DSA_Implementation_Name): This enumeration lists the possible
	implementations of the Partition Communication Subsystem for the
	Distributed Systems Annex (DSA). The three available implementations
	are the dummy stub implementation (No_DSA), and two versions based on
	two different distribution runtime libraries: GARLIC and PolyORB. Both
	the GARLIC PCS and the PolyORB PCS are part of the GLADE distribution
	technology.
	Change the literal GLADE_DSA to GARLIC_DSA to accurately describe
	that organization.

	* rtsfind.ads: Rename RCI_Info to RCI_Locator for better consistency
	between the GARLIC and PolyORB versions of the distributed systems
	annex.
	Remove RE_Unbounded_Reclaim_Pool since it is unused.
