Copy head to stable/9 as part of 9.0-RELEASE release cycle.

Approved by: re (implicit)

Build usr.bin/ with WARNS=6 by default.

Also add some missing $FreeBSD$ to keep svn happy.

Remove empty directories from the HEAD.

Discussed with: developers, imp

Style: move .PATH to where it belongs.

Build this from contrib/ now.

$Header$ -> $FreeBSD$

$Id$ -> $FreeBSD$

Unbreak K&R support, and generate code that works in K&R C as well as
ANSI C no matter what language is specified.

Generate a prototype for initialize_XXXX_error_table() when the language
is set to C.

Simplified using new yacc rules and by not generating y.tab.h. The
lex source is still handled bogusly.

Don't use beforedepend to break things. The usual fix of putting
generated sources in SRCS breaks because compile_et uses an evil
include of one .c file in another. Use a worse fix. Perhaps
DPSRCS is useful after all.

Don't put *.y in SRCS. Put the generated file in SRCS instead.
This fixes incomplete dependencies (mkdep can't work on *.y).

Don't override the default .l.c rule. Just use LFLAGS.

Fixed some style bugs.

Mdoc'ify man page. Use err(3). Remove whoami.

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.

General -Wall warning cleanup, part I.

According to stdlib.h, malloc and realloc return void * but error_table.y
declares them to return char *. For some reason, this causes no problems
with the old compiler tools, but doing a 'make world' with gcc 2.6.3 in a
seperate DESTDIR got me this error:

yacc -d /usr/src/usr.bin/compile_et/error_table.y
cc -O2 -I. -I/usr/src/usr.bin/compile_et/../../lib/libcom_err -I/mnt/usr/include -c y.tab.c -o error_table.o

Stop.

Declaring malloc and realloc to return void * fixes this. It could be that
the new gcc is a bit more picky about these things.

Add y.tab.h to CLEANFILES.

Fix include directive bobble.

Upgrade to latest released SIPB version I can find. (Unfortunately, the
original releases were not numbered.)

Slight makefile cleanup.
