	__alloc_dir.
	(__alloc_dir): Only close descriptor on error if new parameter is true.
	* sysdeps/unix/fdopendir.c (fdopendir): Pass extra argument to
	__alloc_dir.  Don't close fd on error.
	* include/dirent.h (__alloc_dir): Adjust prototype.

	* include/sys/mman.h (__mremap): Add ellipsis.
	* malloc/memusage.c: Adjust mremap wrapper for optional additional
