1998-05-25 Ulrich Drepper <drepper@cygnus.com> * malloc/thread-m.h: Use __mutex_init function in mutex_init macro for Hurd. Patch by Mark Kettenis. 1998-04-18 Gordon Matzigkeit <gord@profitpress.com> * mach/Machrules (+preinit, +postinit): Define these variables to empty because libhurduser and libmachuser don't need startup files. 1998-04-22 Gordon Matzigkeit <gord@profitpress.com> * sysdeps/mach/hurd/errlist.c (ERR_REMAP): Use err_get_code instead of a raw bitmask. 1998-05-23 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * Makeconfig (rpath-dirs): New variable. (rpath-link): Use it. (nssobjdir, nisobjdir, rtobjdir, resolvobjdir): Removed. (db-objpfx): Removed. * crypt/Makefile: Augment rpath-dirs instead of rpath-link. * md5-crypt/Makefile: Likewise. * sysdeps/mach/hurd/Makefile: Likewise. * Makeconfig (move-if-change): New variable. * iconvdata/Makefile (move-if-change): Removed. * manual/Makefile (move-if-change): Set only if undefined, use local script by default. * sunrpc/Makefile (move-if-change): Removed. * sysdeps/mach/hurd/Makefile ($(common-objpfx)stamp-errnos): Use $(move-if-change). * elf/Makefile: Remove all references to obsolete file $(objpfx)rtldtbl.h. ($(objpfx)trusted-dirs.h): Use stamp file. Cleanup command. 1998-05-22 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * elf/dl-close.c (_dl_close): Add debugging message. 1998-05-25 Andreas Jaeger <aj@arthur.rhein-neckar.de> * csu/Makefile ($(objpfx)version-info.h): Correct sed expression to get Linux version and not gcc version. Reported by Alan Curry <pacman@cqc.com>. 1998-05-25 Andreas Jaeger <aj@arthur.rhein-neckar.de> * sysdeps/generic/_strerror.c (__strerror_r): Don't return NULL pointers - return unknown error message instead. Reported by Alan Curry <pacman@cqc.com>. 1998-05-24 Mark Kettenis <kettenis@phys.uva.nl> * iconvdata/Makefile (modules, sed-generated-headers, perl-generated-headers): ibm424.h is perl generated. Make necessary modifications to compile without perl. 1998-05-24 Mark Kettenis <kettenis@phys.uva.nl> * hesiod/hesiod.c (read_config_file): Fix typo.
