	* dwarf2read.c (read_import_statement): Properly set import location
	and destination.
	* cp-support.h (cp_add_using, cp_add_using_directive): Now take char*
	inner, char* outer arguments. Updated callers.

	* gdb.cp/namespace-nested-import.cc: New test.
	* gdb.cp/namespace-nested-import.exp: New test.
