	* elf/Makefile (dl-routines): Add dl-sysdepio.
	* elf/dl-support.c (_dl_sysdep_fatal): Removed.
	* sysdeps/generic/dl-sysdep.c: Move definition of _dl_sysdep_fatal,
	_dl_sysdep_error and _dl_sysdep_warning to ...
	* sysdeps/generic/dl-sysdepio.c: ...here.
	* sysdeps/mach/hurd/dl-sysdep.c: Move the functions to ...

	* sysdeps/unix/sysv/linux/powerpc/dl-sysdep.c: Remove definition
	of functions.
	Bug reported by Marcus G. Daniels <marcus@cathcart.sysc.pdx.edu>.

	* db/Makefile (libdb.so): Depend on libc.so for dynamic loading
	and for Linux ld.so.
	* login/Makefile (libutil.so): Likewise.
	* math/Makefile (libm.so): Likewise.

	* argp-help.c (_help): Supply STATE to argp_args_usage.
	(argp_args_usage): Add filtering of the args doc string.
	(comma): Print cluster headers for the first entry too.
	* argp.h (ARGP_KEY_HELP_ARGS_DOC): New macro.

	Patches by Jean-François Bignolles <bignolle@ecoledoc.ibp.fr>.
	Include <config.h> if HAVE_CONFIG_H is defined.
