This patch ensures that if a project is in a limited with import chain,
it is not reported as a duplicate project.

Tested on x86_64-pc-linux-gnu, committed on trunk

2012-10-02  Vincent Celier  <celier@adacore.com>

	* prj-part.adb (Post_Parse_Context_Clause): Resurrect Boolean
	parameter In_Limited.  Check for circularity also if In_Limited
	is True.
	(Parse_Single_Project): Call Post_Parse_Context_Clause with
	In_Limited parameter.
