* sysdeps/mach/_strerror.c (__strerror_r): Add libc_hidden_def.

	* sysdeps/mach/hurd/pwrite64.c: No libc_hidden_def (__libc_pwrite64).

	* sysdeps/mach/hurd/dl-sysdep.c (__GI_abort): Define alias for abort.

	* include/assert.h (__assert_perror_fail): Declare it, do hidden_proto.
	* assert/assert-perr.c: Add libc_hidden_def.
	* elf/dl-minimal.c [! NDEBUG] (__assert_perror_fail): New function.

	* sysdeps/gnu/errlist-compat.awk: Don't fail if there are no versions
	found at all.
	* sysdeps/gnu/Versions: File removed.  Moved all #errlist-compat
	sys_errlist stuff to ...
	* sysdeps/unix/sysv/linux/Versions: ... here.

	* mach/mach.h: Include <features.h>.
