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.
* mach/Machrules (%.ustamp rule): Pass $(MIGFLAGS-$*) to mig.
(%_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.
(%.udeps): New rule parallel to that one, generating included
makefiles with -M output from `#include <%.defs>'.
* Makerules (sed-remove-objpfx): Remove space before \ at eol.
