* Rules (others): Depend on $(extra-objs), $(install-lib), $(install-bin), $(install-sbin), in object directory. * Makeconfig (link-libc): Don't pass -rpath option with default path, since ld.so should use the same default. * Makerules (build-shlib): Likewise. * Makerules (make-target-directory): Use mkinstalldirs. * sysdeps/mach/i386/sysdep.h: Include unix/i386/sysdep.h to redefine ENTRY et al. * sysdeps/unix/sysv/linux/i386/sysdep.h (NO_UNDERSCORES, ENTRY): Macros removed. The code in unix/i386/sysdep.h should now suffice. * sysdeps/unix/i386/sysdep.h (ALIGNARG): New macro, defns for [HAVE_ELF] and not. (ENTRY): Use it in .align directive. (CALL_MCOUNT): New macro, empty unless [PROF]. (ENTRY): Do CALL_MCOUNT just after the label. * Makeconfig (CPPFLAGS-.po): New variable, use -DPROF so assembly code can call mcount. Tue Feb 20 23:05:16 1996 Roland McGrath <roland@charlie-brown.gnu.ai.mit.edu> * time/private.h, time/zdump.c, time/zic.c: Updated verbatim from ADO; translation markings are now integrated in his distribution. * stdlib/strtod.c (round_and_return): Add missing (mp_limb) 1 cast. * po: New directory where `LANG.po' files for message translations will reside. * po/SYS_libc.pot: New file, template of message strings as in source. * MakeTAGS: New rules to build po/SYS_libc.pot automatically from the source using xgettext. * Makerules ($(..)po/%.pot): New rule. * manual/Makefile (../po/manual.pot): New target, make it empty. * sysdeps/unix/bsd/alarm.c: Moved to sysdeps/unix/alarm.c. * sysdeps/unix/bsd/nice.c: Moved to sysdeps/unix/nice.c. * sysdeps/unix/bsd/stime.c: Moved to sysdeps/unix/stime.c. * sysdeps/unix/bsd/time.c: Moved to sysdeps/unix/time.c. * sysdeps/unix/bsd/utime.c: Moved to sysdeps/unix/utime.c.
