MFC r280387:
xlint: update.

Bring some important updates from NetBSD up to about 2008/04/25.
The main feature is initial support for C99.

Copy head (r256279) to stable/10 as part of the 10.0-RELEASE cycle.

Spelling fixes for usr.bin/

lint: Fix lseek() argument order.

Because SEEK_SET is 0, this seems to have no effect on the generated code.

This now passes a make universe with WARNS=6.

1) Make usage() as dead2 - it helps the compiler know that some vars
are not used uninitialised.
2) Fix some constness problems.
3) Avoid a signedness problem by casting to size_t. If bn != stuff,
than stuff-1-bn should be > 0.

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

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

Pass "-Wtraditional -Wno-system-headers" to compiler as two separate
arguments. GCC4 was unhappy with them combined, while GCC 3.4 did
not care.

Expand *n't contractions.

Move the -Wtraditional warning from the global cpp flags to when the -p
(portability warnings) switch is used. Add -Wno-system-headers after it so
that we dont get 500 screenfulls of warnings about #elif in /usr/include.
I'm not entirely happy with this. Maybe cdefs.h shouldn't use #elif and
instead nest #else clauses?

No, forget about rev 1.24. My system wasn't virgin enough when I tested that.
Restore rev 1.23.

Forget about rev 1.23. -$ is now spelled -fno-dollars-in-identifiers.

Submitted by: kan

GCC 3.3's cpplib does not impliment -$ (forbid the use of $ in identifiers).

Usage style sweep: spell "usage" with a small 'u'.

This commit does not touch anything in src/{contrib,crypto,gnu}/.

Use `The .Nm utility'

FreeBSD prior to 4.4-RELEASE and older versions of 5.0-CURRENT do
not have setprogname(3) and getprogname(3), and we need to build
lint(1) as a cross-tool to bootstrap. Versions from lib/libc/gen
can't be compiled either.

PR: bin/36747

Later versions of gcc object very strongly to the -C flag being passed
as -CC. It makes no difference to gcc in the tree, but this change is
necessary for gcc-3.1 to work.

Make lint(1) a cross-tool.

(See commit log for usr.bin/xlint/Makefile,v 1.11 for what was wrong
with enabling build of lint libraries in rev. 1.12.)

This fixes cross-arch compiles (running binaries for a different arch
when generating lint.7 and lint libraries) and cross-branch compiles
(4.x -> 5.0 buildworld should be working again).

Argh, I constantly keep forgetting about these XXX's I put.

mdoc(7) police:

Restore fixes from revision 1.20 that got lost in revision 1.21 merge.
Fixed some more.

Try harder to lint without nonstandard stuff.

Completeley revert this to the vendor code. This is in preparation to
doing some fixing...

Merge conflicts, fix Makefiles and remove (re)moved file(s).

WARNS=2 fixes.

Expand x{malloc,calloc,realloc,strdup} in-place.
(even found some unchecked naked uses)

mdoc(7) police: fix markup.
(Shows how powerful new -mdoc is.)

Keep my dirty paws off of the $NetBSD$ id's. They're tabbed and should
remain so.

Aesthetics: fix placement of $NetBSD$ (use space instead of tab)

Properly constify the rcsid[].

Change uses of mktemp() to mkstemp().

Call cc -E, not cpp, this allows lint to be unaware of any
machine-dependent defines that cc(1) may normally define.

Change fork() to vfork() and exit() to _exit().

Reuse temporary file so that multiple files passed can be processed without
problems.

Change SYNOPSIS to use mdoc keeps.

Remove single-space hard sentence breaks. These degrade the quality
of the typeset output, tend to make diffs harder to read and provide
bad examples for new-comers to mdoc.

Fix lint for the new cpp. Lint is still broken in other ways, but
this at least allows the use of lint -i on single files again.

Fiddled rcsid to satisfy commitprep.pl; the original NetBSD tag
is still in the comments.

$Id$ -> $FreeBSD$

Add $Id$, to make it simpler for members of the translation teams to
track.

The $Id$ line is normally at the bottom of the main comment block in the
man page, separated from the rest of the manpage by an empty comment,
like so;

.\" $Id$
.\"

If the immediately preceding comment is a @(#) format ID marker than the
the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.

Use __XSTRING() from cdefs.h instead of rolling my own.

I may have forgotten to upgrade this value, but that will never happen
again. (Fully clone the value of __FreeBSD__ from the compiler.)

__FreeBSD__ is also used here.

Cope with the possibility of __FreeBSD__ = 3

.Os NetBSD -> .Os FreeBSD.
The pages are not NetBSD specific and FreeBSD is not a child of NetBSD.

replace 'install' with ${INSTALL}

Well, Jochen adopted most of my submissions. So only the different
style of error reporting (i prefer gcc style to be consistent with the
compiler) is left, plus a minor nit he's most likely been overlooking.

There are still problems with bootstrapping, and you should expect
troubles when linting libc...
