Sun May 12 11:16:58 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu>

	* mach/Machrules (%.udeps rule): Write deps for %_server.[ch] too.
	(%_server.[ch] rule): Don't depend on %.defs; use #include to get
	installed .defs file.

	* stdio-common/vfprintf.c (flockfile, funlockfile): Define to
	nothing for stdio.  Fix fUNlockfile -> funlockfile for libio.
	* stdio-common/vfscanf.c: Likewise.

Sat May 11 13:43:41 1996  Roland McGrath  <roland@delasyd.gnu.ai.mit.edu>

	* hurd/hurdfault.c: Include faultexc_server.h instead of faultexc.h.

	* mach/Machrules (%.ir rule): Don't produce deps for imports.

	* elf/dl-fini.c (_dl_fini): Clear L->l_init_called after calling fn.

	* Makerules (install): Depend on $(slibdir)/libc.so$(libc.so-version).
	[!subdir] ($(libdir)/libc.so, $(common-objpfx)/libc-syms.so): Protect
	these targets and install dep on $(libdir)/libc.so with this.

	* hurd/Makefile: Removed all rules and defns for using code from Hurd
	sources and installing headers from there.

	* sysdeps/mach/hurd/errnos.awk: Set in_mach_errors to FILENAME when we
 	set it.  In Mach error matching clause, only match if FILENAME is
 	still the same value.

	* sysdeps/mach/hurd/Makefile: Don't include sysdeps/mach/Makefile;
	$(mach-srcdir) no longer exists.
	(hurd-srcdir): Variable removed.
	(includes): Don't append -I$(hurd-srcdir).
	(last-includes): Variable removed.
	Remove vpath specs using $(hurd-srcdir).
	(mach-errno-h): New canned sequence.
	($(common-objpfx)errnos.d): New target, generated included makefile
	to determine absolute file names of Mach headers to search for error
	codes and set variable mach-errnos-deps.
	($(common-objpfx)stamp-errnos): Depend on $(mach-errnos-deps) instead
	of prior explicit list.
	(generated): Add errnos.d, stamp-errnos.

	* mach/Machrules (some-if-rtn): New variable and target; compute deps
	of some if routine and make all if routines depend on that .d file
	instead of static list of .h files.

	* mach/Makefile (mach/mach_interface.defs,
	mach/memory_object_user.defs): Targets removed.
	($(objpfx)mach-syscalls.mk): Tweak this kludge so it doesn't depend
	directly on Mach sources.

	* sysdeps/mach/Makefile (mach-srcdir): Variable removed.
	(includes): Don't append -I$(mach-srcdir).
	Remove vpath specs using $(mach-srcdir).

	* hurd/Makefile (server-interfaces): Add faultexc.
	(sig): Remove it from here.
	(fault%.[ch]): Rule removed.
	(MIGFLAGS-faultexc): New variable.

	* hurd/faultexc.defs: New file.

	(%_server.[ch] rule): Likewise.

	* mach/Makefile: Removed all rules and defns for using code from Mach
	sources and installing headers from there.

	* Makeconfig [$(build-shared)=yes] (link-libc): Append
	$(libc.so-version) to libc.so.

	* mach/Machrules (%.ustamp rule): Don't depend on %.defs.

	makefiles with -M output from `#include <%.defs>'.

	* Makerules (sed-remove-objpfx): Remove space before \ at eol.
