* 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.
