	* Makefile (distclean-1): Remove config.cache, config.log, config.h.
	(parent-mostlyclean): Remove all flavors of the parent library.

	* misc/mntent.c (getmntent): Skip multiple whitespace chars
	between fields.

	* hurd/hurdstartup.c (_hurd_startup): If RPC returns
	EXEC_STACK_ARGS flag, get args from stack.
	If args on stack but have info from RPC, relocate args on stack to make
	space for struct hurd_startup_data.
