	* snames.ads-tmpl: Add new standard name Library_Rpath_Options.

2013-10-14  Tristan Gingold  <gingold@adacore.com>

	* sem_prag.adb (Process_Import_Or_Interface): Allow importing
	of exception using convention Cpp.
	* exp_prag.adb (Expand_Pragma_Import_Or_Interface): Expand cpp
	imported exceptions.
	* raise-gcc.c (is_handled_by): Filter C++ exception occurrences.
	* gnat_rm.texi: Document how to import C++ exceptions.

2013-10-14  Jose Ruiz  <ruiz@adacore.com>

	* sem_ch13.adb (Sem_Ch13.Analyze_Aspect_Specification): For
	Priority and CPU aspects, when checking, issue a warning only
	if it is obviously not a main program.

2013-10-14  Tristan Gingold  <gingold@adacore.com>

	* adaint.c: Fix condition for AIX. Minor reformatting.
