* sysdeps/mach/configure.in: Add some checks for Mach headers

	to ensure a sane installation.
	(mach_interface_list): Define this variable by checking for .defs
	files found in various variants.
	* configure.in (mach_interface_list): AC_SUBST this.
	* config.make.in (mach-interface-list): New substituted variable.
	* mach/Makefile (user-interfaces): Define this using the value
	of $(mach-interface-list) instead of mach, mach4.
	Updated other references to mach_interface to use it as well.

	* sysdeps/mach/powerpc/machine-lock.h: Avoid multi-line strings.

	* mach/msgserver.c [NDR_CHAR_ASCII] (mig_reply_header_t): #define as
	mig_reply_error_t for OSF Mach variant.

	* mach/Makefile (routines): Remove bootprivport.
	* mach/bootprivport.c: File removed.  It has never been used.

	* mach/msg-destroy.c (__mach_msg_destroy) [MACH_MSG_PORT_DESCRIPTOR]:
	Grok the OSF flavor of message format.
	(mach_msg_destroy_port): For MAKE_SEND and
	MAKE_SEND_ONCE rights, create an destroy a right to ensure proper
	no-senders notification.

2002-02-06  Roland McGrath  <roland@frob.com>

	* hurd/Versions (libc: GLIBC_2.0): Move cthread_fork, cthread_detach
	to here if 2.0 compatibility enabled ...
	(libc: GLIBC_2.1.3): ... from here.
