[multiple changes] 

2011-08-03  Yannick Moy  <moy@adacore.com>

	* sem_ch4.adb (Analyze_Conditional_Expression): only allow boolean
	conditional expression in ALFA.
	* sem_res.adb (Resolve_Conditional_Expression): mark non-boolean
	expressions as not in ALFA.

2011-08-03  Robert Dewar  <dewar@adacore.com>

	* a-cofove.adb: Minor reformatting.

2011-08-03  Emmanuel Briot  <briot@adacore.com>

	* make.adb, prj.adb, prj.ads, makeutl.adb, makeutl.ads
	(Insert_Project_Sources, Insert_withed_Sources_For): moved from the
	gprbuild sources.
	These packages are more logically placed in the Queue package, since
	they manipulate the queue. It is also likely that they can be adapted
	for gnatmake, thus sharing more code.
	(Finish_Program, Fail_Program): moved from the gprbuild sources, so
	that we could move the above.

2011-08-03  Emmanuel Briot  <briot@adacore.com>

	* errutil.adb (Finalize): clean up the list of error messages on exit.
	Calling this subprogram multiple times will no longer show duplicate
	error messages on stderr.

2011-08-03  Emmanuel Briot  <briot@adacore.com>

	* g-comlin.adb, g-comlin.ads (Set_Command_Line): ignore the parameter
	Getopt_Switches when we have already define a command line
	configuration.

* sem_ch11.adb (Analyze_Raise_xxx_Error): do not mark such nodes as not
in ALFA. Instead, they are considered as assertions to prove.
