	Fix non-only rename list for Fortran modules import.
	* cp-namespace.c (cp_scan_for_anonymous_namespaces): Adjust the
	cp_add_using_directive caller.
	(cp_add_using_directive): New parameter excludes, describe it.  New
	variables ix and param.  Compare if also excludes match.  Allocate NEW
	with variable size, initialize EXCLUDES there.
	(cp_lookup_symbol_imports): New variable excludep, test
	current->EXCLUDES with it.
	* cp-support.h: Include vec.h.
	(struct using_direct): New field excludes, describe it.
	(DEF_VEC_P (const_char_ptr)): New.
	(cp_add_using_directive): New parameter excludes.
	* defs.h (const_char_ptr): New typedef.
	* dwarf2read.c (read_import_statement): New variables child_die,
	excludes and cleanups, read in excludes.
	(read_namespace): Adjust the cp_add_using_directive caller.

	Fix non-only rename list for Fortran modules import.
	* gdb.fortran/module.exp (print var_x, print var_y, print var_z): New
	tests.
	* gdb.fortran/module.f90 (module moduse): New.
	(program module): use moduse, test var_x, var_y and var_z.
