	* prj.adb (Is_Compilable): On first call for a source, cache value in
	component Compilable.
	* prj.ads (Source_Data): New component Compilable, to cache the value
	returned by function Is_Compilable.

2010-10-18  Vincent Celier  <celier@adacore.com>

	* prj-attr.adb: New project level attribute Ignore_Source_Sub_Dirs.
	* prj-nmsc.adb (Expand_Subdirectory_Pattern): New string list parameter
	Ignore.
	(Recursive_Find_Dirs): Do not consider subdirectories listed in Ignore.
	(Get_Directories): Call Find_Source_Dirs with the string list
	indicated by attribute Ignore_Source_Sub_Dirs.
