    Patch 3
	Bash leaves internal quoting in place when expanding array subscripts
	 that appear inside array subscripts in an arithmetic context, causing
	 expansion failures.
    Patch 2
	There are too many differences in the various implementations of shm_open(2)
	 to rely on it for bash's use.
    Patch 1
	In posix mode, `wait -n' with pid arguments does not restrict the set of
	 processes it considers to those arguments.
