Update.

2000-06-29  Ulrich Drepper  <drepper@redhat.com>

	* stdio-common/printf_fp.c (__printf_fp): Don't clobber pointer which
	we later need to calling free().
	Patch by Matt Wilson <msw@redhat.com>.

2000-06-27  David Mosberger-Tang  <davidm@hpl.hp.com>

	* sysdeps/unix/sysv/linux/ia64/bits/ipc.h: New file.
	* sysdeps/unix/sysv/linux/ia64/bits/shm.h: New file.

2000-06-28  Jes Sorensen  <jes@linuxcare.com>

	* sysdeps/ieee754/dbl-64/s_exp2.c: Add include stdlib.h to get
	prototype for abs().
	* sysdeps/ieee754/flt-32/s_exp2f.c: ditto.
