Thu Jun 13 17:25:11 1996 David Mosberger-Tang <davidm@azstarnet.com> cvs/libc-960619

	* sysdeps/generic/memcmp.c: Add prototype decls for internal fns.

	* locale/programs/locale.c: Include string.h.

	* sunrpc/xdr_stdio.c (xdrstdio_getlong), sunrpc/xdr_rec.c
 	(xdrrec_getlong), sunrpc/xdr_mem.c (xdrmem_getlong): Make sure
 	appropriate sign-extension is performed on machines with
 	sizeof(long) > 4.

	* sunrpc/xdr.c (xdr_int, xdr_u_int): If sizeof(long)==8 and
 	sizeof(int)<sizeof(long), we need to go through a temporary
 	variable.

	* locale/programs/ld-numeric.c: Include <alloca.h>

	* libio/stdio.h (__libc_fatal): Add prototype.

	* libio/cleanup.c: Use __P() to declare prototype when __STDC__ is
 	in efect.

	* libio/iopopen.c (read_or_write, parent_end, child_end): Declare
 	volatile to avoid "might get clobbered by longjmp" warning.

	* features.h (__KERNEL_STRICT_NAMES): Define __KERNEL_STRICT_NAMES
 	unless _LOOSE_KERNEL_NAMES is in effect (which, with high
 	probability is a sure loser).
	* sysdeps/unix/sysv/linux/gnu/types.h (__KERNEL_STRICT_NAMES): Remove.

	* sysdeps/unix/bsd/osf/alpha/start.S (errno): Removed.
	* sysdeps/unix/sysv/linux/alpha/start.S: Ditto.

	* misc/paths.h (_PATH_MAN): Change from /usr/share/man to /usr/man
	to be Linux FSSTND compliant.

Mon Jun 10 17:50:31 1996  David Mosberger-Tang  <davidm@azstarnet.com>

	* sysdeps/unix/sysv/linux/alpha/pipe.S: Use PSEUDO.

	* sysdeps/unix/sysv/linux/alpha/sysdep.S,
 	sysdeps/unix/sysv/linux/alpha/brk.S,
 	sysdeps/unix/sysv/linux/alpha/ieee_get_fp_control.S,
 	sysdeps/unix/sysv/linux/alpha/ieee_set_fp_control.S,
 	sysdeps/unix/sysv/linux/alpha/llseek.S,
 	sysdeps/unix/sysv/linux/alpha/sigsuspend.S,
 	sysdeps/unix/sysv/linux/alpha/syscall.S: Rename syscall_error to
 	__syscall_error to avoid intruding application name space.

	* sysdeps/unix/sysv/linux/alpha/sysdep.h: Rename __NR_get?id
	to SYS_get?id so that syscall stubs in sysdeps/unix define
	these syscalls in terms of getxpid/getxuid/getxgid.

	* sysdeps/unix/_exit.S, sysdeps/unix/getegid.S,
 	sysdeps/unix/geteuid.S, sysdeps/unix/getppid.S,
 	sysdeps/unix/execve.S, sysdeps/unix/fork.S,
 	sysdeps/unix/syscall.S: Terminate syscall with PSEUDO_END.

	* sysdeps/unix/make-syscalls.sh, sysdeps/unix/sysdep.h
 	(PSEUDO_END): Rename END() to PSEUDO_END().

	* sysdeps/unix/alpha/sysdep.h: Move error-handling code in PSEUDO
 	to PSEUDO_END to improve branch-prediction.  Include .frame
 	directive to make syscalls debugabble.
	(PSEUDO_END): New macro.

	* sysdeps/unix/alpha/sysdep.h, sysdeps/alpha/bb_init_func.S,
 	sysdeps/unix/sysv/linux/alpha/brk.S: Use ldiq instead of ldi since
 	latter is illegal under DEC Unix.

	* sysdeps/unix/alpha/sysdep.S: Renamed from
	sysdeps/unix/sysv/linux/alpha/sysdep.S.  This file works for OSF/1
 	as well.
	* sysdeps/unix/bsd/osf/alpha/sysdep.S: Remove (note that the
 	EWOULDBLOCK -> EAGAIN mapping was unnecessary since
 	EWOULDBLOCK==EAGAIN under DEC Unix and Linux/Alpha).

	* sysdeps/alpha/divrem.h: Use retaddr instead of ra as the return
 	address register in the .frame directive.

	* sysdeps/alpha/copysign.c: Remove.

	* sunrpc/rpc/types.h: Include <sys/param.h> and <netinet/in.h> to
 	avoid RPC definitions of INADDR_LOOPBACK and/or MAXHOSTNAMELEN.

	* errno.h: Move __END_DECLS to correct place to make file
 	compilable under c++.

	* dirent/dirent.h: Document _DIRENT_HAVE_D_OFF macro.  Define
	d_ino only if <direntry.h> hasn't defined d_fileno.

	* configure.in (HAVE_ASM_WEAKEXT_DIRECTIVE): Reverse order of
	arguments to weakext to make .weakext detection work on ECOFF systems.

	* FAQ: Add Linux/Alpha to list of supported platforms.  Mention
	that _validuser() has been replaced by __ivaliduser().

Thu Jun  6 21:39:38 1996  David Mosberger-Tang  <davidm@azstarnet.com>

	* sysdeps/unix/bsd/sun/sunos4/tcsetattr.c (tcsetattr): Declare cmd
 	as unsigned long, not as int (to avoid incorrect int->long
 	promotion).
