	* gnat_rm.texi, s-oscons-tmplt.c: Minor typo

2009-09-17  Emmanuel Briot  <briot@adacore.com>

	* gnatcmd.adb, prj-proc.adb, make.adb, prj-ext.adb, prj-ext.ads,
	makeutl.adb, makeutl.ads, clean.adb, prj-pars.adb, prj-pars.ads,
	prj-conf.adb, prj-conf.ads, prj-tree.adb, prj-tree.ads, prj-proc.ads,
	prj-nmsc.ads (Add, Value_Of, Reset): new parameter Tree.
	Scenario variables are now specific to each project tree loaded in
	memory.
	Code clean ups.

	* exp_disp.adb (Make_DT): Remove wrong line of code that was
	undocumented and probably added by mistake.
