1997-05-31 02:33  Ulrich Drepper  <drepper@cygnus.com>

	* io/ftwtest-sh: More tests.

	* misc/tsearch.c: Rewrite tdestroy_recursive.

	* libio/libio.h: Define bits for libg++-2.8.

1997-05-30 22:21  Thorsten Kukuk  <kukuk@vt.uni-paderborn.de>

	* nis/nss_nis/nis-hosts.c: Same changes as in
	nss/nss_files/files-hosts.c (Always use inet_pton).
	* nis/nss_nisplus/nisplus-hosts.c: Likewise.

1997-05-30 09:50  Richard Henderson  <rth@tamu.edu>

	* manual/maint.texi: ECOFF hasn't been tested in ages and I don't
	plan on doing so ever again.  Don't say alpha-linuxecoff is known
	to work.

	* elf/dl-lookup.c: Include <alloca.h>.
	* misc/tsearch.c: Include <string.h>.
	* posix/execle.c: Include <alloca.h>.
	* posix/execlp.c: Likewise.
	* stdio-common/printf_fphex.c: Include <string.h>.
	* sunrpc/xdr.c: Include <string.h>.
	* sysdeps/generic/memccpy.c: Include only <string.h>.

	* sunrpc/clnt_udp.c (clntudp_call): Make fromlen a size_t to fix
	parameters to network functions.
	* sunrpc/pmap_rmt.c (clnt_broadcast): Likewise.
	* sunrpc/svc_tcp.c (svctcp_create): Likewise with `len'.
	(rendezvous_request): Likewise.
	* sunrpc/svc_udp.c (svcudp_bufcreate): Likewise.
	(svcudp_recv): Similar, but go through a local variable.  The old code
	used &xprt->xp_addrlen.  Someone should determine if the type of the
	structure member should be changed instead.
	* sunrpc/xdr_rec.c (xdrrec_create): Expunge a ptr->int cast warning
	and transform a nonsense for-loop to a closed form calculation.
	(fill_input_buf): Another ptr->int warning.

	* sysdeps/alpha/Makefile: Temporarily turn on -mieee globally.  This
	will last until I figure out how to build a parallel libm_ieee.

	* sysdeps/alpha/fpu/fclrexcpt.c,
	* sysdeps/alpha/fpu/fegetenv.c,
	* sysdeps/alpha/fpu/fegetround.c,
	* sysdeps/alpha/fpu/feholdexcpt.c,

	* sysdeps/alpha/fpu/fgetexcptflg.c,
	* sysdeps/alpha/fpu/fraiseexcpt.c,
	* sysdeps/alpha/fpu/fsetexcptflg.c,
	* sysdeps/alpha/fpu/ftestexcept.c: New files.  There is, btw, a small
	kernel patch that must be applied as of 2.0.31-pre1 and 2.1.41 for
	this to work properly.

	* sysdeps/alpha/fpu/fpu_control.h: Update copyright.  Change default
	FP mode to round to nearest, no exceptions as for Intel.
	* sysdeps/unix/sysv/linux/alpha/setfpucw.c: Add copyright.
	(rdfpcr): Use excb rather than trapb.  Be more efficient about
	getting at the fpcr.
	(wrfpcr): Likewise.
	(__setfpucw): Reformat.

	* sysdeps/ieee754/huge_val.h: Change GCC's HUGE_VAL definition to use
	a single DI-mode integer instead of bytes.  This produces better code
	on Alpha.  Similar for HUGE_VALF.
	* sysdeps/ieee754/nan.h: Similar for NAN.  Add NANF and NANL.

	* sysdeps/libm-ieee754/s_log2.c: Missing */ and weak_alias.

	* sysdeps/unix/alpha/sysdep.S: Tiny cleanups.
	* sysdeps/unix/sysv/linux/alpha/syscall.S: Likewise.
	* sysdeps/unix/sysv/linux/alpha/brk.S: Don't use jmp macro to make
	sure the stack frame is released the very instruction before the
	real jump out.
	* sysdeps/unix/sysv/linux/alpha/ieee_get_fp_control.S: Likewise.
	* sysdeps/unix/sysv/linux/alpha/ieee_set_fp_control.S: Likewise.

	* sysdeps/unix/sysv/linux/alpha/gnu/types.h: Undef some bits we may
	have gotten from <linux/posix_types.h>.

	* sysdeps/unix/sysv/linux/alpha/ioperm.c: Add definition for Miata.

1997-05-30 13:05  Ulrich Drepper  <drepper@cygnus.com>

	* misc/tst-tsearch.c (mangle_tree): Update casts to prevent
	warnings.

1997-05-29 14:02  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* sysdeps/unix/sysv/linux/sys/ttydefaults.h (CEOL, CSTATUS): Use
	correct value for _POSIX_VDISABLE.

1997-05-29 13:59  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* Makefile (manual/dir-add.texi): Force execution.

1997-05-29 13:57  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* sysexits.h: New file.

1997-05-29 13:55  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* stdlib/strfmon.c: Don't run past EOS after `='.
