Vincent Celier ddd6e5ae32 prj-nmsc.adb (Check_Ada_Name): For children of package A... 
2006-10-31  Vincent Celier  <celier@adacore.com>

	* prj-nmsc.adb (Check_Ada_Name): For children of package A, G, I and S
	on VMS, change "__" to '.' before checking the name.
	(Record_Ada_Source): Always add the source file name in the list of
	of sources, even if it is not the first time, as it is for another
	source index.
	(Get_Unit): Replace both '_' (after 'a', 'g', 'i' or 's') with a single
	dot, instead of replacing only the first '_'.

	* prj-part.adb (Parse): Convert project file path to canonical form

	* prj-proc.adb (Recursive_Process): Make sure that, when a project is
	extended, the project id of the project extending it is recorded in its
	data, even when it has already been processed as an imported project.
