Update.

1997-03-29 17:39  Ulrich Drepper  <drepper@cygnus.com>

	* math/Makefile (routines): Add carg, s_ccosh and s_csinh.

	(main): Add calls to csinh_test and ccosh_test.

	* misc/Makefile (tests): Add tst-tsearch.
	Add rule to link tst-tsearch against libm.
	* misc/tsearch.c: Rewritten to use Red-Black-Tree algorithm by
	Bernd Schmidt <crux@Pool.Informatik.RWTH-Aachen.DE>.
	* misc/tst-tsearch.c: New file.

	* stdio-common/bug5.c: Clear LD_LIBRARY_PATH environment variable
	before using system.

1997-03-29 16:07  Ulrich Drepper  <drepper@cygnus.com>

	* sysdeps/posix/system.c: Update copyright.

1997-03-29 04:18  Ulrich Drepper  <drepper@cygnus.com>

	* elf/dl-error.c (_dl_catch_error): Add another argument which is
	passed to OPERATE.
	(_dl_receive_error): Likewise.
	* elf/link.h: Change prototypes for _dl_catch_error and
	_dl_receive_error to reflect above change.

1997-03-28 21:14  Miguel de Icaza  <miguel@nuclecu.unam.mx>

	* elf/dl-error.c: Manually set up the values of "c", this avoids a
	call to memcpy and a zero 152 bytes structure.

	* sysdeps/sparc/dl-machine.h (elf_machine_rela): Test
	RTLD_BOOTSTRAP to avoid performing relative relocs on a second
	pass.

	* sysdeps/sparc/udiv_qrnnd.S: Make the code PIC aware.

	* sysdeps/unix/sysv/linux/sparc/Dist: Add kernel_stat.h and
	kernel_sigaction.h

	__getservbyname_r() not getservbyname().
	(BROKEN_LIKE_POSIX): Define to 1 so we get strict POSIX behaviour.
