Add section .note.GNU-stack for assembly files used by 386 and amd64.

Remove hand-written labs/abs implementations. GCC is smart enough.

It turns out GCC generates code that's a couple of bytes big bigger, but
performs no branching whatsoever.

Remove unneeded stores back into the function arguments.

Submitted by: Christoph Mallon

Add missing END() macros, as per rev 184547 for amd64. The lack of these
is mostly harmless, but it does upset some of valgrind's functionality.

Per Regents of the University of Calfornia letter, remove advertising
clause.

# If I've done so improperly on a file, please let me know.

Eliminate gdtoa.mk and move its contents to ${MACHINE_ARCH}/Makefile.inc.
The purpose of having a separate file involved an abandoned scheme that
would have kept contrib/gdtoa out of the include path for the rest of libc.

Replace our ancient dtoa/strtod implementation with the gdtoa
package, a more recent, generalized set of routines. Among the
changes:
- Declare strtof() and strtold() in stdlib.h.
- Add glue to libc to support these routines for all kinds
of ``long double''.
- Update printf() to reflect the fact that dtoa works slightly
differently now.

As soon as I see that nothing has blown up, I will kill
src/lib/libc/stdlib/strtod.c. Soon printf() will be able
to use the new routines to output long doubles without loss
of precision, but numerous bugs in the existing code must
be addressed first.

Back out the -fpcc-struct-return fixes.

Approved by: re (rwatson)

Import newer versions of div() and ldiv() from NetBSD which handle
the -fpcc-struct-return calling convention properly instead of
returning garbage. This may break backwards compatibility with some old
binaries that were compiled when -fno-pcc-struct-return was the default.

Standardize on our SCM ID style.

Restore CSRG ID's lost in January 1995.

De-orbit DEFS.h - the other arches do not use it, and it got replaced
with <machine/asm.h>.

Removed duplicate VCS ID tags, as per style(9).

$Id$ -> $FreeBSD$

Handle machine-dependent (stdlib) sources more automatically.

This fixes bugs in the manual handling. abs.[cS] was handled too
specially and the wrong (.c) variant for each of div.[cS], labs.[cS]
and ldiv.[cS] was added to SRCS. This caused the .c variant to be
used if `depend' was made and the .S version to be used otherwise.

Revert $FreeBSD$ to $Id$

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

First round of changes to clean up the RCSID mess in libc:

1) Changed LIB_SCCS and SYSLIB_SCCS to LIB_RCS and SYSLIB_RCS.
2) Changed sccsid[] variables to rcsid[]
3) Moved all RCSID strings into .text
4) Converted all SCCSID's to RCS $Id$'s
5) Added missing $Id$'s after copyright.

(Very) minor improvement from NetBSD/J.T.Conklin.

First crack at making libc work with the new make macros. It compiles on
my machine, and a simple static (genassym) and shared (sysctl) executable
both work. Still to be done: RPCand YP merge.
