Update.

1999-12-07  Scott Bambrough <scottb@netwinder.org>

	* sysdeps/arm/dl-machine.h (elf_machine_rel): Fixup R_ARM_PC24
	relocs if possible.

1999-12-06  Andreas Schwab  <schwab@suse.de>

	* sysdeps/unix/sysv/linux/setrlimit.c: First find out wether the
	ugetrlimit syscall exists.

	* sysdeps/unix/sysv/linux/getrlimit.c: Only put versions on
	exported symbols.
	* sysdeps/unix/sysv/linux/setrlimit.c: Likewise.
