	* s-stchop-vxworks.adb: Add comment.

2009-11-30  Emmanuel Briot  <briot@adacore.com>

	* make.adb, prj.adb, prj.ads (Compute_All_Imported_Projects): Now acts
	on the whole tree, to better share code with gprbuild.
	(Length): New subprogram, to share code in gprbuild.
	(Project_Data): Remove fields that are only needed when compiling a
 	project in gprbuild (where we use local variables instead)
	* osint.adb, osint.ads: Added minor comment on memory management
