* 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.

/* Schedule an alarm. In SECONDS seconds, the process will get a SIGALRM.

If SECONDS is zero, any currently scheduled alarm will be cancelled.

The function returns the number of seconds remaining until the last

alarm scheduled would have signaled, or zero if there wasn't one.
