* sysdeps/unix/sysv/linux/dl-osinfo.h (dl_fatal): Remove inline

	from definition.

	* sysdeps/x86_64/dl-machine.h (elf_machine_rela): Don't define
	label if it is not used.

	* elf/dl-profile.c (_dl_start_profile): Define real-type variant
	of gmon_hist_hdr and gmon_hdr structures and use them.

	* elf/dl-load.c (open_verify): Add temporary variable to avoid
	warning.

	* nscd/nscd_helper.c (get_mapping): Avoid casts to avoid warnings.

	* sunrpc/clnt_raw.c (clntraw_private_s): Use union in definition
	to avoid cast.

	* inet/rexec.c (rexec_af): Make sa2 a union to avoid warnings.
	* inet/rcmd.c (rcmd_af): Make from a union of the various needed types
	to avoid warnings.
	(iruserok_af): Use ss_family instead of casts.

	* gmon/gmon.c (write_hist): Define real-type variant of
	gmon_hist_hdr structure and use it.
	(write_gmon): Likewise for gmon_hdr.

	* sysdeps/unix/sysv/linux/readv.c: Avoid declaration of replacement
	function if we are not going to define it.
	* sysdeps/unix/sysv/linux/writev.c: Likewise.

	* inet/inet6_option.c (optin_alloc): Add temporary variable to
	avoid warning.

	* libio/strfile.h (struct _IO_streambuf): Use correct type and
	name of VTable element.
	* libio/iovsprintf.c: Avoid casts to avoid warnings.
	* libio/iovsscanf.c: Likewise.
	* libio/vasprintf.c: Likewise.
	* libio/vsnprintf.c: Likewise.
